The best international sim cards for travel | an in-depth data plan buyer’s guide for traveling abroad.

How to find the best international SIM Card and eSIM data plan.

phones and technology

Ensuring your phone has high-speed data when you travel internationally is a confusing and frustrating process for many travelers—in fact, it’s one of the most-asked questions I get from readers. That’s why I wanted to help remove the mystery around international data plans by creating this guide to the best international SIM cards.

Traveling to Europe? Check The Savvy Backpacker’s Guide To Smartphones, SIM Cards, and Data Plans in Europe , my guide to How To Buy A SIM Card For Europe , and my guide to the best eSIM Data Plans For Europe .

International SIM Cards vs Single-Country/Local SIM Cards vs Global SIM Cards

Choosing the best international SIM card can be confusing because there are a ton of options and each has its own positives and negatives. So let’s start by defining the overall SIM card categories:

• International SIM cards can often be purchased before your trip so they can be mailed to you before departure or you can download the eSIM if your phone is compatible.
• International SIM Cards will be slightly more expensive than local SIM cards but they’re more convenient—especially if you’re using an eSIM.
• Buying a Local SIM is often the most affordable option but you have the added hassle of having to hunt down a SIM Card after you arrive, dealing with language barriers, and you may need to register the SIM before activation (which may require you to submit your passport and provide a local address)
• NOTE: By EU law, any SIM card bought in the EU will work in any other EU country with no extra charges.
• Global SIM cards are notoriously bad . They’re often run by faceless companies with no customer support and they seem to always have connection issues—just do a search on Amazon and you’ll see a ton of negative feedback. You also typically pay way more and get way less data.
• However, I am a fan of the Orange Holiday World SIM card since it’s owned by Orange—which is one of the largest mobile providers in the world but data is limited in some countries.

E-SIM Data Plans vs (Physical) SIM Card Data Plans

Up until a few years ago, you had to physically remove the plastic SIM card from your phone and install a new SIM card if you wanted to connect to a new mobile provider.

However, many modern phones now let you download a digital eSIM to your phone so you no longer have to deal with physically removing any SIM cards. eSIMs are way more convenient because you don’t have to track down a SIM card and you can often install multiple eSIM cards on your phone (in addition to your physical SIM) so you can have multiple plans on a single phone.

Not all data providers currently offer eSIM data plans so you might have limited plan options—but I imagine this will become the standard over the next few years.

What To Look For In An International SIM Card

Are you still confused about international SIM cards? Don’t worry.

Here are some common things to keep in mind when researching and evaluating all the various international data plan options.

Some SIM Card Plans Are Data Only

Every SIM data plan has different terms when it comes to calls and texts. Many are data only—i.e. no calls or texts. Or some come with local calls and texts but don’t let you make international calls or texts. And others let you make worldwide texts and calls.

Data-only plans tend to be the cheapest while plans that offer worldwide calls/texts are the most expensive.

NOTE: Apple iMessage is sent via data so they’ll work with data-only plans (assuming you’re sending an iMessages to other Apple users). You can also use apps like WhatsApp via data so data-only is typically sufficient.

Not All SIM Data Plans Allow Data Tethering

Data-tethering (i.e. using your phone as a hotspot for other devices like your computer, etc.) isn’t allowed on all data plans so keep that in mind when choosing a data plan.

Global SIM Cards Offer Different Data Limits For Different Countries

Global SIM cards often group countries into different “zones” and each zone will have different data allowances.

For example, “zone one” countries might give you 10GB of data, but “zone two” counties could only give you 5GB of data, and then “zone three” countries might only give you 500MB of data. Check the plan details before buying.

Check The International SIM Card Plan’s Validity Period

Most international SIM cards are valid anywhere from seven to 30 days once you activate your card.

This is something you’ll obviously want to pay attention to since you don’t want your plan to expire before your trip ends. Some plans will let you “top-up” your plan so you can add extra time without having to buy another SIM card, but you’re often only allowed one or two “top-ups” before needing to buy another plan.

Your Phone Must Be Unlocked

Some phones are “carrier locked”—i.e. they’re digitally programmed to only work on your mobile provider’s network. This means it won’t work if you install another network’s SIM card until it’s “unlocked.”

Most mobile providers will unlock your phone if you request it so inquire before leaving as it might require a visit to the store or a few emails/phone calls with tech support.

Best International SIM Cards and eSIM Cards by Region

There isn’t a single “best” international SIM card for everywhere in the world but each region has some good options so that’s why I’ve broken this section down by region.

Orange Holiday World (Great SIM Card For Most Countries In The World)

The Orange Holiday World is a very popular choice for world travelers because it covers just about everywhere in the world and it’s backed by Orange—most “world” SIM cards are backed by no-name companies.

The main downside is that the data plan only lasts for 14 days so it’s not ideal for longer trips but you can top up the card one time for €29 to get another 14 days of service with an additional 10GB of data.

• PRICE:  $50
• DATA:  10GB
• INCLUDES TEXTS OR CALLS?:  NO
• USED AS A MOBILE HOTSPOT?:  Yes
• CREDIT VALID FOR:  14 Days

The Orange Holiday World plan includes 10GB of 4G/LTE data in many countries but there are a few “zones” that have a lower data limit.

Zone 1 (10GB data included) Europe:  Andorra, Azores, Aland islands, Austria, Balearic islands, Belgium, Bosnia and Herzegovina, Bulgaria, Canary Islands, Corfu, Crete, Croatia, Cyprus, Cyclades islands, Czech Republic, Denmark, Estonia, Faroe Islands, Finland, France mainland, Germany, Gibraltar, Greece, Guernsey, Hungary, Ireland, Iceland, Italy, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Isle of Man, Norway, Netherlands, Poland, Portugal, Rhodes, Romania, Spain, United Kingdom, San Marino, Sardinia, Serbia, Sicily, Slovakia, Slovenia, Switzerland, Sweden, Ukraine, Vatican

Other countries:  Algeria, Armenia, Australia, Saudi Arabia, Benin, Botswana, Brazil, Burkina Faso, Canada, Cameroon, Chad, Chile, China, Congo, Egypt, Gabon, Ghana, Guinea Bissau, Guinea Conakry, Hong Kong, India, Indonesia, Israel, Ivory Coast, Japan, Jordan, Kenya, Korea (south), Kuwait, Liberia, Macao, Madagascar, Malaysia, Mali, Mauritius, Mexico, Moldova, Montenegro, Morocco, Mozambique, Niger, Nigeria, New Zealand, Uganda, Peru, Qatar, Central African Republic, Democratic Republic of Congo, Russia, Senegal, Sierra Leone, Singapore, South Africa, Taiwan, Tanzania, Thailand, Tunisia, Turkey, UAE, USA, Vietnam

Zone 2 (5GB data included) Albania, Argentina, Bahrain, Colombia, Costa Rica, Ecuador, El Salvador, French Polynesia, Guatemala, Honduras, Iraq, Nicaragua, Oman, Panama, Dominican Republic, Uruguay

Zone 3 (1GB data included) Afghanistan, Belarus, Cambodia, Cape Verde, Equatorial Guinea, Kazakhstan, Pakistan, Paraguay, Philippines, Sri Lanka, St Vincent and the Grenadines, Togo, Venezuela

Zone 4 (50MB data included) Rest of the world

HOLAFLY ESIM (Unlimted Data eSIM Plans)

Holafly  is a new data-only eSIM provider that I recently used in Italy—the service was great and I got very fast data speeds (read my  Holafly eSIM Review  to learn more). They sell both country-specific and regional data plans. Unlike other companies, Holafly’s plans give you unlimited data and their plans run from 5 to 90 days (they will throttle your data if you use excessive data).

• 5 Days: $19
• 10 Days: $34
• 15 Days: $47
• 20 Days: $54
• 30 Days: $64
• 60 Days: $84
• 90 Days: $99
• Service Speed:  5G/4G/LTE
• Calls:  None
• Texts/SMS:  None
• Tethering:  No

Orange Holiday Europe eSIM and Physical SIM (Two Great Options For Europe)

The  Orange Holiday Europe SIM Card  and the Orange Holiday Europe eSIM Card are probably the best all-around options for European data because you get a good amount of data for a reasonable price—and it includes worldwide calls and text.

NOTE: Buy the Orange Holiday Europe eSIM Card if your phone is eSIM compatible since you’ll save on shipping fees and eSIMs are more convenient than physical SIM cards.

Additionally, Orange is one of the largest mobile companies in the world and they have great coverage throughout most of Europe.

Plan Specs:

• DATA:  30GB
• CALLS:  Unlimted in Europe and 1200 minutes worldwide
• TEXT:  Unlimted in Europe and 1000 worldwide
• CAN BE USED AS A MOBILE HOTSPOT?:  Yes

Orange Holiday Zen eSIM and Physical (Cheaper Option For Europe)

If you need less data and want to save a little money, check out the  Orange Holiday Zen SIM  and the Orange Holiday Zen eSIM —both are great all-around options for European data because you still get a solid amount of data for a reasonable price. Both plans also include worldwide calls and texts.

• Price:  $29.90
• Data:  15GB
• Service Speed:  4G/LTE
• Calls:  Unlimited within Europe and 30 min outside of Europe.
• Texts/SMS:  Unlimited within Europe and 200 outside of Europe.
• Credit validity:  14 day
• Data tethering allowed
• Usable on any device (phones, tablets, hotspots…)
• Cards come with a French phone number

AIS eSIM2FLY Global (eSIM that covers much of the world)

After the Orange Holiday World SIM, the AIS eSIM2FLY Global is another good option that doesn’t quite have as much data but it has the benefit of being an eSIM (so you don’t have to deal with shipping fees).

PRICE:  $49.90 DATA:  6GB INCLUDES TEXTS OR CALLS?:  NO CREDIT VALID FOR:  15 Days

MORE TIPS ON USING YOUR MOBILE PHONE INTERNATIONALLY

BUY A PORTABLE BATTERY CHARGER

Using apps like Google Maps and taking photos kills your phone battery so a portable battery is a must-have. I use  Anker PowerCore 10000  because it’s tiny and affordable but there are multiple options.

USING FREE WIFI WHILE TRAVELING ABROAD

I think people overestimate how easy it is to find free wifi in abroad. Yes, free wifi is becoming more prevalent throughout the world—however, it’s hard to rely exclusively on free wifi since it can be a pain to actually find a free network when you actually need it.

The best places to find free wifi are McDonald’s, Starbucks, cafés, coffee shops, and hostels/hotels — but getting connected is rarely super convenient, reliable, or fast.

Relying on free wifi fails when it comes to day-to-day stuff like using Google Maps, looking up restaurant reviews via Google/Trip Advisor/Yelp, using random apps, using Uber, booking e-tickets, using email, etc. because these are things you typically do spur of the moment. That’s why I prefer to have the option of having mobile data because having to seek out a coffee shop every time I want to use the internet gets tiring very quickly.

HOW TO LOWER YOUR MOBILE DATA USAGE

Data can be expensive and it’s extremely easy to unknowingly burn through a lot of data because many apps use data in the background. Facebook, email, Instagram, Snapchat… those all constantly use data throughout the day without you knowing it. That’s it’s important to know how to limit your data usage.

USE AIRPLANE MODE AND BLOCK DATA TO SPECIFIC APPS

I’ll put my phone in Airplane Mode because that disables all data (but GPS still works in Airplane Mode). You can also go into the settings and disable data access to each individual app. I’ll go in and turn every off except for things like Google Maps or others that I’ll use more frequently — this way when I turn off Airplane Mode only those apps that will use data. Then I’ll turn Airplane Mode back on when I’m done.

DOWNLOAD OFFLINE MAPS

Google Maps lets you download entire city maps so they can be used offline. As an added bonus, GPS doesn’t use data so offline Google Maps works fairly well (but not all functionality works). Here is a good  YouTube video  that explains everything.

MAKE CALLS OVER WhatsApp

WhatsApp is an excellent app for free calling and text messages—I’ve found that most people outside the US exclusively use WhatsApp to communicate (including many Airbnb hosts).

Embarking on an adventure across borders? A SIM card for international travel can be your lifeline, keeping you connected without breaking the bank . With roaming charges resembling a relic of the past, savvy travelers know that switching to a local or global SIM can make all the difference.

But in a sea of options, where do you start? From understanding different types available to knowing what makes one stand out—let's dive into making your travels smoother and more connected.

Benefits of using a SIM card for international travel

Before we delve into the practical information, let’s talk about the main benefits of using a SIM card for international travel.

Nowadays, it's hard to find someone who doesn't mind being offline while traveling abroad. After all, a good internet connection allows us to use our phone as a GPS, connect with friends and family back home, research places to see or where to eat, work remotely, book accommodation and transportation during the trip, etc. 

There are different ways to stay connected while you’re abroad, like looking for Wi-Fi spots, activating roaming plans offered by your home carrier or purchasing local SIM cards upon arrival. But there are some advantages that make international SIM cards a good choice for many travelers.

For starters, you’ll avoid excessive roaming charges in case your home company doesn’t offer good international packages. You’ll also be able to make sure that the SIM card is compatible with your phone , without any surprises when you're already at the destination.

And of course, there’s the convenience of being connected as soon as you land . That makes it much easier to tell folks back home that you’ve arrived safely, to find cost-effective and easier ways to get to your accommodation (using apps like Uber, for instance), etc. You won’t have to worry about looking for a local SIM card or a Wi-fi spot , which makes your trip smoother from the start.

Comparing different types of SIM cards for international travel

Advantages and disadvantages of local sims.

Buying a local SIM at your destination can be a budget-friendly move. Many shops sell them, and it can be a good choice if you’re staying in one country for a long time.

• Often the cheapest option
• Get a local number for your stay
• Avoid roaming fees entirely
• Have to find and buy the SIM when you land
• May not work if your phone is carrier-locked
• Need a new SIM for each country you visit

Advantages and disadvantages of international SIMs

International SIMs are made to keep you connected across borders . Physical or eSIM, the benefits are the same. 

• One SIM covers multiple countries
• Cheaper than pay-per-use roaming
• Manage your plan from an app
• Keep your regular number active
• More expensive than local SIMs
• Rates and coverage vary by country
• May not have a local number for calls

Advantages and disadvantages of eSIMs

A more recent invention, eSIMs are a type of international SIM card that doesn't have a physical form; you simply activate it online. The beauty is its convenience: no physical swapping , just tap to activate.

• Instant setup - download and go
• No need to find a local SIM abroad
• Can store multiple eSIMs on your phone
• More secure than physical SIMs
• No risk of losing your home SIM
• Requires an eSIM-compatible phone
• Not available from all carriers yet
• Some countries still require physical SIMs

Other types of SIM cards for international travel

Travel sim cards.

A travel SIM card is made to work across multiple networks in different countries. Unlike a local SIM that only works in one place, a travel SIM has you covered worldwide.

International data SIM Cards

If you're mainly after better data rates for your phone or tablet on the go, check out international data-only SIM cards. They usually offer good data packages and low rates.

Global SIM Cards

Want it all? A global SIM card typically includes a European and U.S. number, with the option to add more international numbers. It's the ultimate in flexibility for the frequent jetsetter.

Regional SIM cards

These are only available in a certain region or continent. That means they might be cheaper of offer better coverage in that area, but won't work in other parts of the world (or will work, but with worse coverage or extra fees). 

What to consider when selecting an international SIM card

When looking for the right SIM abroad, here are a few things to research and think about:

• Coverage area - will it work at all your stops?
• Data plans - how much do you need for your trip? How can you top it up if needed?
• Call rates - is the SIM data-only or does it allow you to make regular calls? Are the rates reasonable for international calls?
• Expiration - how long is the SIM card valid?
• Compatibility – are you sure it will work on your device?
• Activation process – how easy is it to set up?

Top international SIM card providers

If you’re looking to buy an international SIM card in preparation for travel across multiple countries, you can do it online.

Ready to explore your international SIM card options? Let's check out a few top providers.

This option has a wide coverage area, making it one of the best travel SIMs for those traveling between multiple countries and regions. You can choose between e-SIM and traditional SIM cards and generally have a reliable coverage.

Breeze eSim

They offer coverage in over 245 mobile networks in more than 150 countries, as well as multiple networks per country for increased coverage. Beware that they only offer eSIMs, so check if your phone is compatible.

This is focused on internet access for professional travelers, offering high speed internet in over 200 countries. They provide both a regular plastic SIM card (with global express delivery) and a digital eSIM , delivering data connection for almost any device. You can refill your data online, anytime.

Orange Holiday Europe

Headed to Europe? The Orange Holiday SIM covers 30 countries with generous data plans. It’s easy to install and to top-up and can be used across multiple European countries without changing your preferences on your phone.

Discover Global e-SIM Card

This can be used worldwide but has one of the best coverages of popular Asian countries , being a good choice if you’re planning on travel around there. However, like most other eSIMs, it doesn’t allow calling and texting.

Other options to consider are GigSky, TravelSim, Ultra Mobile, KnowRoaming, and KeepGo.

How to use an international SIM card

Got your travel SIM? Let's get it up and running for your trip. Most international SIMs need to be activated online or by phone before use. For eSIMs, the activation process is usually easier. The SIM will then work alongside your regular SIM.

Physical SIM cards require swapping out your home SIM, unless your phone has two SIM slots. Just make sure you keep it somewhere safe , and remember where it is, so you can switch it back when you fly home.

Topping up your international SIM card

Most providers let you top up your balance or data online . For example, with Orange Holiday Europe, you just log in and add credit using your SIM number. This lets you re-up your talk, text, or data limits as needed during your travels.

Before buying your SIM card for international travel, look into how you can top it up, whether by checking their website or reaching out to their sales or support team.

Troubleshooting common issues

If you hit a snag with your travel SIM, don't panic. Some quick fixes:

• No signal - check coverage maps, move to a new area, restart your phone
• Can't make calls - make sure you have an active plan, dial the right country code
• Data not working - confirm data roaming is on, reset network settings

Still stuck? Reach out to your SIM provider's customer service team for help.

Maximizing your international SIM card experience

To get the most out of your travel SIM, keep these tips in mind:

• Consider both convenience and affordability. Sometimes investing a bit more can spare you time and hassle.
• Don't pay for more than you need. Estimate your usage based on your trip plans. A smaller data bucket may be plenty for maps and messaging.
• Are you planning on using it for streaming, video calls, or hotspot the internet to your laptop? Go unlimited.
• Always check if the SIM card is compatible with your phone.
• If possible, avoid buying a SIM at the airport, since they often charge extra.
• Ensure there are easy ways for recharging your card. Especially when you’re traveling for a long time, being able to top it up through an app makes a big difference.
• If you’re calling home from your travel SIM, you can reduce costs by using Wi-Fi calling apps like Skype or Whatsapp, buying an international calling package from your SIM provider and checking if your plan includes free calls to certain countries.

So, whether it’s avoiding eye-watering bills, feeling more confident to travel around distant destinations or just staying in touch with those back home, a sim card for international travel might make all the difference. As you’ve seen, picking a good one isn’t rocket science—it's common sense wrapped in a bit of savvy shopping.

5 Best International SIM Cards for Travel in 2024

Home | Travel | 5 Best International SIM Cards for Travel in 2024

When traveling abroad, get a policy from one of the  best travel insurance companies . Y ou can get a  5% discount   on Heymondo , the only insurance that pays medical bills upfront for you, HERE!

International SIM cards let you use mobile data abroad and, in some cases, make and receive calls while traveling without accruing hefty roaming fees.

I never travel without getting one of them first, because if you use your usual phone plan outside your country, you will have to pay for roaming, and that will drastically increase your phone bill. For this reason, it is better to use a global travel SIM when traveling.

For all our adventures abroad, we use the  Holafly eSIM cards , which offer unlimited data in many countries at a fairly reasonable price. While these SIM cards don’t include calls in most countries, they often have unlimited data so that you can make voice and video calls with apps like Messenger, Skype, and WhatsApp. If that sounds good to you, and you want to get a SIM card for your next trip, don’t forget to get a discount on Holafly .

5% OFF your international eSIM card

While we’re super satisfied with the international eSIMs from Holafly, I’ll share a few more options in this guide, including physical SIM cards for international travel . I also recommend reading our guide on how to travel cheaply and taking advantage of all the travel discounts available . After all, your phone bill is just one of the things you can save on while exploring the world!

International SIM cards, the best way to avoid roaming

There are several worldwide SIM cards that let you have Internet while traveling . In this guide, I’ll explain the different options and share other tips to help you find the perfect fit:

• International SIM card prices

Best international SIM cards

How much data should an international sim card have, is there a global sim card that works in every country, finding a global sim that’s compatible with your device.

• How to install a SIM card for international travel

Global data SIM cards are great for leisurely trips, but if you’re traveling for work or school and need to have your laptop or tablet connected to the internet, you’re better off getting a portable Wi-Fi device . We use the Solis router from Skyroam , and it really comes in handy !

Global SIM card prices

We’ve been using the international prepaid SIMs from Holafly for years, but there are other options like SimOptions , Airalo , KeepGo , and Knowroaming . If you need help deciding which one to get, check out the table below to compare global SIM card prices :

To sum up, Holafly is the only international SIM with unlimited data in almost every destination, so it’s a super convenient option. That said, depending on where you’re going, it may not be the cheapest choice. Another thing to consider is that Holafly only has eSIM cards, so if your phone isn’t compatible with digital cards, you’ll need to get a physical card, such as the one from SimOptions .

To help you choose the best international SIM card for your needs, I’m sharing the details for each of the top options below.

1. Holafly , an international SIM with unlimited data

First, Holafly is the best international data SIM card , offering unlimited data plans for most countries at a pretty affordable price. This allows you to browse the Internet, post on social media, use Google Maps, and stay in touch with loved ones via messaging apps like Skype, Telegram, and WhatsApp.

Something you should keep in mind is that Holafly’s plans are data-only, so you can’t make or receive calls abroad (the only exception is the international SIM cards for Europe ). However, this isn’t an issue since you can use apps like Skype and Telegram to make voice and video calls.

Moreover, Holafly’s cards are totally digital , so you don’t have to worry about removing your usual SIM and inserting a new one into your device. All you have to do is scan the QR code in your email and follow the installation instructions . It helps to print out the QR code or download it to another device so you can scan it on your mobile phone. Also, make sure your device is compatible with the global SIM card by checking here .

Most destinations have international SIM plans for five days or more, so it’s easy to find one that suits your trip. This year, we’ve traveled around the world and visited more than 10 countries, and Holafly has always given us great service . You can read more about our experience in our Holafly review .

Of course, it wouldn’t be fair if I didn’t tell you about the disadvantages of using Holafly. The main drawback is that you can’t share data with other devices , so each traveler must buy their own international SIM card . Despite this, I still think Holafly is the best option for most travellers.

Also, don’t forget that you can get a discount on your Holafly eSIM!

2. SimOptions , the best physical international SIM card for travelers

If your phone isn’t compatible with eSIM technology, then the physical international SIM card from SimOptions is the best alternative. That said, it’s worth noting that SimOptions offers both conventional SIM cards and digital international SIM cards .

In addition, the company has a wide variety of country cards with different validity durations and amounts of data. SimOptions also allows data sharing, but the cards have limited data, so it’ll be much easier to run out of GBs.

To buy an international SIM from SimOptions, just order through this link . Physical cards take about three business days to arrive, and I recommend ordering in advance so you can install it and sort out any potential issues. Installation is super simple since all you have to do is insert the SIM into your device’s card slot and follow the on-screen instructions.

While SimOptions is a great choice, it’s not my favorite. I prefer to have an international SIM card with unlimited data , like the one from Holafly . With SimOptions, the cards typically include 10 GB or 30 GB of data, which is enough for about a two-week trip if you limit your videocalls and social media usage.

3. Airalo , another popular international SIM to avoid roaming fees

Airalo is another way to avoid roaming with an international SIM . Like Holafly, all the cards from Airalo are virtual, so you must be sure your device is compatible with eSIM technology. The installation process for this global SIM is similar to Holafly in that you must scan a QR code that gets sent to your email. Just follow the activation instructions, and you’re ready to go.

The main benefit of Airalo is that it offers international SIMs for several countries , so if you’re visiting multiple destinations during your trip, you can get by on just one SIM card.

All of Airalo’s plans include limited data and, depending on the destination, validity for 7, 15, or 30 days. If you plan to share your data with other travelers or devices, be aware that you’ll run out of data pretty quickly.

Weighing the pros and cons of Airalo global plans, I think the price per GB is quite high. It could be better to buy a international SIM card  from Holafly for each country you visit.

4. KeepGo , another global SIM card for your trip overseas

KeepGo offers prepaid international SIM cards , but it works a little differently than the others that I mentioned. In this case, you pay for a set amount of data, and the card is valid for one year within a given geographic area.

Also, KeepGo only has virtual international SIM cards , so you should check your device’s compatibility before buying one.

This company isn’t my first choice since the price per GB is more expensive compared to other companies. You can see the prices and data amounts in the chart below:

5. KnowRoaming , another international SIM card for foreign travel

The last company I’ll talk about is KnowRoaming , which has digital international SIM cards . You’ll receive your card via email immediately after purchasing, and all you have to do is scan the QR code to install it on your device. Of course, your phone must be compatible with eSIM technology to use the cards from this company.

While KnowRoaming’s customer support is available 24 hours a day, the company has some drawbacks that you should know about. First, the price per GB is quite high compared to other options. Secondly, all of its cards have limited data, so it may not be a great deal depending on how much data you consume.

Finally, KnowRoaming doesn’t have global SIMs in as many countries as Holafly and SimOptions . You can buy their SIM card with worldwide coverage , if necessary, but this also has limited data, so it may end up costing you more money.

One of the most common questions when looking for an international mobile SIM card is how much data it should have. To give you a rough idea, I created a comparison chart showing common apps and phone uses and how much data each one consumes, taking into account my average consumption while traveling:

As you can see, voice and video calls consume the most mobile data. If you only use your global SIM card for things like Google Maps and search, or to post on social media, a prepaid international SIM with limited data could be fine. Of course, keep in mind that if you plan on sharing data with a travel companion, you’ll end up using up your data twice as fast, so a limited data plan could fall short.

If you want to make calls with family and friends while traveling, an international SIM with unlimited data , like one from Holafly , is your best bet. You could also try setting a daily limit on your data consumption, turning off your device’s data when not in use, and, when possible, using the Wi-Fi in hotels, restaurants, and other public places.

What is the best international SIM card for travel?

After comparing the best global SIM cards on the market, I think the cards from Holafly come out on top. Most of Holafly’s plans offer unlimited data, so you can use your favorite apps and make calls without worrying about running out of GBs.

Just remember that Holafly only has virtual cards, so if your device isn’t compatible with eSIM technology, you can’t use them. The next best option is SimOptions , which offers physical and digital international SIM cards . For most countries, the lowest data plan includes 10 GB for 14 days.

Both Holafly and SimOptions have 24/7 customer support, so you can contact them if you run into any issues.

International eSIMs vs. physical international SIM cards

Whether it’s an international eSIM or a convenient international SIM card , it will have the same function. So, in that sense, one option isn’t better than the other. It’s the format of the card that you must consider since virtual international SIM cards use a newer technology that’s not compatible with all devices.

As long as your phone is compatible, eSIMs are much more convenient and practical since you don’t have to remove your usual SIM card to use them. In addition, you can buy an eSIM anytime, even if you’re already traveling, since it arrives via email. As a result, eSIM cards reduce plastic use and transportation, making them more environmentally friendly. This is why I believe that in the future, all international SIM cards will be digital .

If your phone isn’t compatible with eSIM technology, the best option is to get a physical international global SIM like the ones from SimOptions .

Only Airalo and KnowRoaming have international SIM cards that work for all countries (or almost every country). Holafly also has some multi-country cards that include several countries in Europe, Latin America, Asia, North America, and the Caribbean. So, if you’re going to visit several countries, it may be worth considering this type of global SIM card .

Holafly’s multi-country SIM, a global eSIM that works in many countries

Holafly offers several multi-country cards, which are perfect if you plan on visiting several countries back to back. It’s a virtual international SIM card , so all you have to do is scan the QR code in your email to connect to the mobile network automatically.

Below, you can see the different global SIMs you can get through Holafly:

Airalo global SIM, an international SIM card you can use anywhere

Airalo also offers an international prepaid SIM that works in almost every country. Once you install the card, you’ll automatically connect to the best mobile network in that country.

However, unlike Holafly , Airalo’s worldwide SIM cards have very limited data, so it’s easy to run out, even if you only use basic applications. I recommend checking Airalo’s data limits to determine if it’s enough mobile data for your trip and phone use. It may be worth buying different international SIMs from Holafly for shorter durations as you visit each country.

KnowRoaming global SIM, another worldwide SIM card

KnowRoaming is another company that has SIM cards with coverage in several countries . However, with this card, you would have the same problem as with Airalo: very limited data. Depending on what you’re going to use your worldwide SIM for, it may not have enough data, so it may be better to buy several Holafly cards of shorter duration.

Pros and cons of using an international SIM card for travel

Using a SIM card for international travel has its benefits and drawbacks, although I think the pros outweigh the cons:

Buying a global SIM card may add an extra cost to your trip, but it’s worth it, especially when you factor in how expensive roaming is. Personally, I wouldn’t travel abroad without an international SIM that lets me connect to the Internet and stay in touch with loved ones. I’ve been using the global SIM from Holafly for years now, and if you decide to get one of your own, use the 5% discount.

How to choose an international SIM card

Before you get a new SIM card for international travel , it’s important to check its compatibility with your phone and the amount of data it offers .

In the case of international eSIMs , they’re not compatible with all phones. Holafly, Airalo, KeepGo, and KnowRoaming only offer global eSIMs , while SimOptions has both digital and physical international SIM cards .

As for data, the amount offered by each card varies. Some international SIM cards have unlimited data , while others have limited data that wouldn’t even be enough for regular phone use. Holafly is the only company that offers unlimited data, with just a few exceptions, making it the most convenient option in this regard.

Another thing to consider when getting an international SIM card for travel is customer support. Holafly and SimOptions offer 24/7 customer service via chat, so you can get help from them no matter where you are in the world. KeepGo and KnowRoaming have limited customer support hours, while Airalo doesn’t offer this service at all.

Taking all these factors into account, I highly recommend Holafly as the best international SIM overall, although SimOptions is the best in terms of compatibility .

It’s crucial that you check your phone’s compatibility before buying a global SIM card . You should also make sure that your phone is unlocked . Otherwise, you won’t be able to use any kind of international SIM card .

When it comes to compatibility, be aware that all new phones accept virtual international SIM cards , but older models may only be compatible with physical SIMs. You can check here to see a complete list of phone models that are compatible with virtual data cards.

Again, physical SIMs are usually compatible with all devices. However, if your phone doesn’t have a dual SIM slot, you’ll have to remove your usual SIM so you can insert the international SIM card . In the case of SimOptions, they offer three SIM card formats: Standard, Micro, and Nano, so you’re sure to find one that works for you .

How to activate a SIM card for international travel

If you have a physical SIM, you must first remove your usual SIM card so you can insert the new one. Of course, if your device has a dual SIM slot, you can have both SIM cards inserted at the same time. Once you insert the global SIM card , you’re ready to use it.

If you have an international eSIM , scan the QR code on the device on which you want to have mobile data. I recommend printing out the QR code or downloading it to another device with a screen.

Here is how to activate an international SIM card on an Android device:

• Go to Settings > Connections >  SIM Manager > Add SIM .
• Scan the QR code , which you should have printed or downloaded to another device.
• Follow the instructions and steps that will appear on the screen.
• Open Settings > Connections > SIM Manager
• In preferred SIM, click on Mobile data and select the eSIM to install .
• Go to Connections and enter Mobile networks to activate Data Roaming and for the eSIM to be fully activated.

For those with an iOS device, here are the activation instructions:

• Go to Settings > Mobile network > Add data plan .
• Open Settings > Configuration > Mobile network
• Select the eSIM to install and activate Data Roaming .

In just a few simple steps, you can install your global SIM card and start using it to access the Internet. It’s a good idea to do this before your trip so you can contact the company’s customer support team if you run into any issues.
