Best eSIMs for Global Travelers 2026

An eSIM (embedded SIM) is a SIM built into your phone, tablet, or smartwatch that you activate digitally instead of inserting a plastic card. You add a plan by scanning a QR code, using a carrier's app, or following the prompts in your phone's settings. Most eSIM devices can store several profiles, so you can keep your home number and add a local or travel data plan without swapping cards.

Check the basics first, then compare plans:

Most recent flagship phones and many mid-range models support eSIM, including iPhone XS, XR, and later, Google Pixel 3 and later, and recent Samsung Galaxy S and Z models. Support can vary by country and carrier, so check your exact model. Your phone must also be unlocked, or locked to the carrier selling the eSIM, before you can add another provider's plan. A quick test on many phones: dial *#06#, and if an EID number appears, the device has eSIM hardware.

On most Android phones you can check in a minute:

Every iPhone from the XS and XR onward supports eSIM, and iPhone 14 and later models sold in the U.S. are eSIM-only, with no SIM tray. To confirm on your phone:

Most eSIMs are installed by scanning a QR code from the provider in your phone's cellular or SIM settings, or by tapping an install link in the provider's app. Some carriers also activate an eSIM during phone setup or transfer it from your old phone. Install a travel eSIM while you still have Wi-Fi, ideally before departure, then turn on that line and its data roaming when you arrive. Keep the QR code private, as many codes work only once.

Yes, on most eSIM phones. Dual-SIM phones can keep a physical SIM and an eSIM active at the same time, for example your home number for calls and texts plus a travel eSIM for data. Many phones can store several eSIM profiles, but usually only two lines can be active at once. In settings, choose which line handles mobile data so you don't accidentally roam on your home plan.

Yes, eSIMs can carry mobile data, calls, and texts just like a physical SIM, but what you get depends on the plan. Many travel eSIMs are data-only, so you would make calls through apps such as WhatsApp or FaceTime, or use Wi-Fi calling. Plans from mobile carriers, and some travel plans, include a phone number with minutes and SMS. Check the plan details before you buy.

eSIMs are generally at least as secure as physical SIM cards. They use the same carrier authentication, and because the profile is built into the phone, a thief can't simply remove it and use it in another device. The main remaining risk is SIM-swap fraud, where criminals trick a carrier into moving your number. Set a PIN on your carrier account, lock your phone with a passcode, and use app-based two-factor authentication instead of SMS codes where possible.
