What is the Best SIM Card for International Travel in 2025?

While traveling abroad is always a great opportunity to tune out and disconnect from the chaos of everyday life, it can also be extremely challenging to find yourself in a new country without any source of connection to your surroundings. Paying for an international phone plan can be expensive, but luckily it’s possible to find a source of connection without breaking the bank.

International SIM cards give you the best of both worlds. Here you’ll find the best SIM card for international travel for every type of traveler. There are endless options out there and the best one will depend on your travel plans. All in all, international SIM cards offer an affordable and temporary opportunity to stay connected while traveling abroad by giving you access to your phone and wireless data across multiple countries around the world. Another option is to purchase mobile top-ups through apps like Boss Revolution, which can send top-ups to over 270 carriers in more than 100 countries.

Why use an international SIM?

No need to ditch your connection while you’re off on your international adventure. The best travel SIMs have you covered!

International SIM cards unlock a whole new travel experience. While it can be tempting to ditch the phone on your next overseas adventure, having access to data while traveling abroad is important for two reasons: It keeps you safe and makes travel a whole lot more convenient.

After all, it’s not always possible to rely on WiFi when traveling abroad, and unless you have an expensive international phone plan, you risk being stranded in an unfamiliar place without basic information to make travel fun, safe, and easy.

International SIM cards are a bit different from local SIM cards. While it’s possible to buy local SIM cards when you arrive at your destination, these are best suited for travelers who are staying in one location for an extended period of time.

Local SIM cards can be a great option for those studying or working abroad, but if you’re traveling for shorter stints or across multiple countries, buying a local SIM card in each destination can be a hassle. International SIM cards give you access to data across multiple destinations and are often considered the best travel SIMs if you want to have the freedom to cross borders.

Where to buy your international SIM card

Stay in touch with your bestie from back home with an international SIM card.

If you want to stay connected throughout your travels and are wondering where to buy international SIM cards to prepare for your trip, there are a few things to keep in mind when weighing your options. Ask yourself:

• Where are you traveling?
• For how long will you travel?
• Are you going to multiple countries or one destination?
• What do you plan to use your phone for while abroad?

If you’re planning to stay in one location for an extended period of time, you can often buy local SIM cards when you arrive in the country. But if you want to buy an international SIM card in preparation for travel across multiple countries, your only option is to purchase one online.

Do your research on the best SIM card for international travel and consider which one suits your needs best. Once you weigh the pros and cons and work out the nitty gritty of your trip abroad, you can pre-purchase the best international SIM card for you online before you go. Then you’re ready to hit the ground running when you arrive at the destination of your dreams.

You'll be covered in more than 190 countries through their various bundles. Plans can be purchased for specific countries within the regions where they have coverage.

They provide affordable data coverage in over 50 countries—and even complimentary access to 1100 airport lounges globally in case of flight delay!

• Base cost: $0
• Monthly cost: Varies per region and country, but starts from $1/1GB trial on the global pack to $28 / month for 10GB data, valid 30 days when connected overseas

4. Nomad

• Pros: Nomad is one of the best travel SIMs for travelers in Europe and the USA because it is an official partner to some of the top networks in both regions, allowing travelers to stay connected to more than 500 networks across over 100 countries. One of the perks of Nomad is its lifetime plan option. If you frequently travel abroad and want to stick with the same international SIM card for all of your overseas escapades, you can purchase data packages that are valid for one year—and if you top up within the year, you can continue to use your SIM the next year too.
• Cons: Similar to GigSky, Nomad is a data-only SIM, which means you won’t be able to make calls or send texts abroad. It also requires you to input part of the SIM number when topping up data, which means you’ll have to keep track of this for years if you plan to keep using the card for future travels.
• Coverage area: All of Europe plus Algeria, Anguilla, Antigua and Barbuda, Argentina, Armenia, Aruba, Australia, Azerbaijan, Barbados, Bermuda, Bolivia, Brazil, British Virgin Islands, Canada, Cayman Islands, Chile, China, Colombia, Costa Rica, Dominica, Dominican Republic, Ecuador, Egypt, El Salvador, Georgia, Greenland, Grenada, Guadeloupe, Guatemala, Honduras, Hong Kong, India, Indonesia, Israel, Jamaica, Japan, Kazakhstan, Kuwait, Macao, Malaysia, Mexico, Montserrat, Myanmar, Netherlands Antilles, New Zealand, Nicaragua, Pakistan, Panama, Paraguay, Peru, Philippines, Puerto Rico, Qatar, Reunion, Russia, Saudi Arabia, Singapore, South Africa, South Korea, St. Lucia, St. Vincent and Grenadines, Suriname, Taiwan, Thailand, Trinidad and Tobago, Tunisia, Turkey, Turks and Caicos, USA, Uruguay, Venezuela, and Vietnam.

5. OneSimCard

• Pros: Thanks to its wide coverage area, OneSimCard is one of the best travel SIMs for those who are traveling between multiple countries and regions. This is another eSIM, which means you won’t have to worry about removing and keeping track of your original SIM card or juggling between multiple SIMs as you travel across borders. Unlike other eSIMS, you can opt for a data+call package, which allows you to make international calls while abroad.
• Cons: One of the biggest cons to OneSimCard is that the website isn’t very user-friendly compared to other international SIM cards. That means purchasing and top ups may be a little more difficult than other options. OneSimCard is also a more expensive option, as you don’t get as much data for your investment.
• Coverage area: Europe, Asia, Middle East, and Africa.
• Base cost: $20
• Monthly cost: Ranges from $20-$100, depending on location 

6. easySIM

It’s one of the cheapest and best international SIM cards for Europe that includes calls, texts, and data, and one of the best travel SIMs for Latin America.
• Cons: One of the biggest cons to using Three UK is the process for topping up your data. If you plan to travel for more than 30 days, you can only top up your data using a UK registered credit card. This is no big deal for UK residents, but if you don’t have access to a UK card, you’ll only be able to use the plan for calls and texts after the first month.
• Coverage area: All of Europe plus Australia, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Hong Kong, Indonesia, Israel, Macao, New Zealand, Nicaragua, Panama, Peru, Puerto Rico, Singapore, Sri Lanka, Uruguay, United States Virgin Islands, USA, and Vietnam.
