The Best International SIM Cards Are eSIMs


The best SIM cards travel aren’t physical SIM cards, they’re eSIMs. If you’re just here to look at the comparison of the best providers, skip to the 6 best eSIM providers for travelers.

But if you’re new to eSIMs, read on to see what they are and why you need one.

eSIMs Are How You Stay Connected Abroad

Getting data while you’re traveling is one of the most critical components that make digital nomads and remote workers successful. And yes - you can freeball it and rock up to a foreign city, not knowing the language, not knowing where you’re going to stay, and not even knowing how to tell the cab driver to go to the center of town.

Ok Davey Crockett - have fun with that. We’ve got an 11am Zoom call we’ve got to make.

So how can you be sure you’re going to have data anywhere on Earth?
Enter the mighty eSIM.

What Are eSIMS And Why Travelers Need Them

eSIMs are electronic SIM cards that you can download which provide you with service to a mobile data and cellular provider.

You can have a physical SIM card and an eSIM simultaneously in your phone without issue.

The only catch is that you have to make sure your phone;

  • Doesn’t have a carrier lock
  • Supports eSIM technology

Common eSIM-compatible phones include:

  • iPhone XS and newer
  • Google Pixel 3 and newer
  • Samsung Galaxy S20 and newer
  • And many more. A simple web search can provide clarity if you're unsure.

The Benefits Of An eSIM

  1. No Data Roaming Fees: Traditional domestic providers like Verizon would LOVE you to turn on your data while you’re abroad. They’re able to hit you with huge data roaming fees and other charges.
  2. Convenience: eSIMs eliminate the need for physical SIM cards. You simply scan a QR code or download a mobile plan without the hassle of swapping cards or buying data packages in a foreign language.
  3. Multiple Plans: eSIMs allow users to store multiple plans/profiles on a single device. This is perfect for nomads who move between countries and need to switch between local and international plans.
  4. Increased Connectivity: As eSIM adoption grows, more carriers worldwide are offering eSIM plans. This allows remote workers and digital nomads to easily connect to data and hotspot if their wifi goes out, ensuring better coverage and often cheaper rates.

Do You Need An eSIM For International Travel?

No, you don’t. You have the option of buying a physical SIM card on arrival to a country, buying a data plan and popping that SIM into your phone.

And if your phone only supports one eSIM and one physical SIM, and you want to keep your eSIM for your US number to receive OTPs and 2FAs and buy local physical SIM cards for data.

But if your phone supports multiple eSIMs - then keeping your home number on an eSIM and getting a local eSIM are definitely the way to go.

Final Thoughts

eSIMs are absolutely the way of the future, and the technology has reached a place where there’s no excuse not to be using them.

But whether you use an eSIM for your US or local number depends on how many eSIMs your phone can handle, and whether you need to use your US number while you’re abroad. There’s no one-size-fits-all here, so you should pick whichever one fits your situation best.
