If you’re traveling, there’s a good chance you’ll need to access your phone on the road. Although you can certainly get international calling on your United States phone, it can be expensive.
Fortunately, these best international sim cards can save you money and keep you connected at all times.
What Are the Best International Sim Cards?

Why You Need an International SIM Card
You need an international sim card for several reasons, precisely convenience, and safety. International calling plans can be extremely expensive, especially if you’re traveling for long periods.
You could rack up huge costs without knowing it and be stuck with a giant bill when you return to the United States. Even if you install an international plan on your phone, you will still probably pay more than you would with an international sim card.
Going with no sim card at all can be dangerous. Sometimes you need to access your data, and there are no safe WiFi options around. There’s also a good chance that you could have to make a call while abroad.
Also, open WiFi networks are not always that safe. Accessing your banking information on an available network is ill-advised, and even checking your email can pose some risks. It’s a good idea to play it safe and get an international sim card.

Finding the Best International Sim Card
Trying to find the best international sim card for your needs can be slightly daunting. There are a few things that you should keep in mind before making your decision. Thinking it through will yield the best option in the end.
How Often Will You Be Moving?
Plenty of sim cards work in one part of the world, but that’s it. However, if you will be moving around a lot, especially between continents, you will want a sim card that is as flexible as you are.
Make sure that you read the fine print before making your decision.
Do You Have a Business Number?
Often, you’ll get a new phone number with your sim card. While this is entirely ordinary and expected, it can wreak havoc on your business if you use your American phone number for work.
In cases like this, it’s a good idea to either get a sim card that allows you to keep your number or get an eSim card.
What’s the Length of Your Trip?
Your trip’s length will dictate what you should look for in a sim card, specifically when it comes to things like data packages.
If you’re not sure how long you’re going to be gone, it’s not a bad idea to opt for a “pay as you go” package.
Do You Need a Phone, Data, or Both?
Many international sim cards come with both phone and data packages, although some are one or the other. Think about what you’re going to use your phone for, and act accordingly.
If you only need one or the other, you’ll wind up paying less and making the most out of your international sim card.
Keep these considerations in mind when purchasing your international sim card, and you’re more likely to make an informed decision.
Frequently Asked Questions
If you’re still not sure how to find the best international sim card for you, don’t worry. These frequently asked questions will help clear up any confusion and help you become confident in your decision.
Can I Use Applications Like WhatsApp and Facebook Messenger With an International SIM Card?
Yes, all of your applications will work with an international sim card. So, for example, although WhatsApp acts a lot like a texting service, it’s a web application that doesn’t have much to do with your sim card number. You’ll still be able to log into Facebook, Instagram, and other applications as yourself with your new number.
Can I Use My International SIM Card as a Hotspot?
You can use many international sim cards as hotspots, although some are better than others. If you need a hotspot for working abroad or for any other reason, check the information on your sim card. It’s also a good idea to read reviews to make sure that the card you’re looking at will do what you need it to.
What Is the Difference Between a Mobile SIM and a Data SIM Card?
Mobile sim cards let you do everything you usually would with your phone number, including making calls, texting, and using limited data through the sim card itself. Data sim cards provide you with specific data packages where you can access the internet or applications from your phone.
What’s the Difference Between a Local SIM Card and an International SIM Card?
Local sim cards are ones that you buy specifically from a phone carrier in the country that you’re visiting. Often, ex-pats will get local sim cards rather than international ones because they’re staying for months or years on end. Local sim cards tend to be less expensive, but they’re not as ubiquitous, and you can only really use them in one country. So if you’re traveling around a lot, it’s a good idea to get an international sim card.
How Do I Use an International SIM Card?
For physical sim cards, remove your sim and replace it with the new one. For eSim cards, you need to log online and install them.
So, What’s the Best International SIM Card?
What constitutes the best international sim card comes down to your preferences and needs. The seven choices on our list are a good jumping-off point and can help you hone down your decision to select the perfect one for your travel needs. Happy travels!
