The 6 Best eSIMs For International Travel

Traveler activating eSIM for data abroad


Table Of Contents


If you head abroad to work remotely, for a work trip or just for a vacation - it's time to get an eSIM for international travel. Gone are the days of popping your national SIM card out, popping an international SIM card in, and promptly losing your national SIM card (they're so small!).

But eSIMs can be confusing, especially if you've historically just tacked on an international package to your domestic plan when you went abroad.

Here's the deal - eSIMs are going to save you money, save you time, and are just flat out easier than buying a physical SIM card for that trip abroad or buying an international package with your domestic provider.

So - here's what eSIMs are, how to use them, and the 6 best eSIMs for international travel.


About eSIM Cards For International Travel And How They Work

What Are International eSIMs

International eSIMs are virtual SIM cards that are tied to a local national carrier, which means you'll get mobile data in the country you're visiting. The main advantage of these eSIMs is getting local mobile data in whichever country you're visiting.


This means while some eSIMs for international travel offer a local number, that's not as common. And if you're not living in the country longterm, you probably don't need a local number anyway.

How International eSIMs Work

International eSIMs (and all eSIMs, for that matter) are available on apps like Airalo, Holafly and others. On these apps you buy packages that range anywhere from 1 - 30 days, and these come with a set amount of data. 

You can download an international eSIM before you enter or while you're in-country, although most eSIMs won't activate until they connect to cell tower in the local country.

This means you can buy a 7-day data eSIM for Japan (or any other country) well before your trip, because the eSIM isn't activated until it connects to a local cell tower.

How To Download & Activate An eSIM For International Travel (iPhone)

Step 1: Download your preferred eSIM app and create an account.

Step 2: Select your country and then the package that best suits you.

Step 3: Now to activate, most apps will guide you through the activation process step by step.

Step 4: During this activation flow, you'll be asked to select which line you'd like for your Cellular Data. Make sure to set "Cellular Data" to the local line you're activating.

Step 5: If for some reason your local line isn't activated, go to Settings>Cellular and tap your freshly activated line (example below).

Step 6: Activate data roaming

Once you've confirmed your international eSIM is active, make sure you enable "Data Roaming" (example below). This is important!

The Benefits Of An International 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 remote workers who want to use their US number to receive OTPs and 2FAs, as well as those who need to switch between their local country's phone service and international plans.
  4. Increased Connectivity: The ability to hotspot from anywhere means you'll stay connected regardless of power outages (remote workers know this can be a huge problem in more isolated areas).


Phone Requirements For International eSIMs

  1. Your phone must support eSIM technology. 
  2. Your phone must not be carrier locked
    • To check if your iPhone is carrier locked, go to Settings>General>About, then scroll down to "Carrier Lock".
    • You should see "No SIM restrictions".
    • If you see anything other than this, contact your carrier to have the lock removed.

                                        FAQ About eSIMs For International Travel

                                        Q: Do I Need An eSIM For International Travel?

                                        A: While an eSIM for international travel is higher on the convenience scale, you don't need an international eSIM. 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. 

                                        Q: Can I use an eSIM if my phone supports dual SIM cards?

                                        A: Yes. And if your phone supports dual eSIM cards, you'll be able to have multiple eSIMs installed (although you'll only be able to activate two at a time). 

                                        Q: What's the difference between an international eSIM and an international plan?

                                        A: These two are very different; an international eSIM means you're buying an eSIM specifically to get data in a certain country/region outside your home country. An international plan means you're just buying an "international data package" from your current provider. More on these below.

                                        eSIMs For International Travel

                                        Getting an eSIM for international travel means you're downloading an app like Airalo and purchasing a local eSIM for 1-30 days with a local data package so that you have local data in the country you're visiting.

                                        Keep in mind this means you will not be able to make or receive calls to your US number during this time. But as long as your US number is an eSIM, or you have the physical SIM for your US number in your phone, you should be able to receive SMS for verification codes.

                                        When doing this, make sure to turn off data roaming for your domestic line.

                                        International Plan

                                        This consists of you contacting your domestic carrier and asking them to give you their international package. While this is a more expensive option, with this you should be able to send and receive calls and texts to and from your US number, and you'll also have local data.

                                        Opting for an international plan over an international eSIM is ok for short-term trips (less than a week), but anything longer than that and you'll probably want to switch to an eSIM to avoid huge charges from your carrier.

                                        Q: Can eSIMs be used internationally?

                                        A: Yes, in fact that's what many eSIMs are made for. But to be clear, the "e" in eSIM doesn't make it an international tool. The provider you buy that eSIM from gives you the power to use your phone internationally.


                                        Final Thoughts On eSIMs For International Travel

                                        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.
