Is your phone ready?

A-Sim eSIMs work on most phones from 2018 and later. A few quick checks before you buy:

Running iOS 17.4 or later. (XR, XS, 11, 12, 13, 14, 15, 16 series all supported.)

Android 9 (Pie) or newer

Most Pixel, Galaxy S20+, OnePlus 8+, Xiaomi 11+ phones support eSIM.

Carrier-unlocked phone

If you bought your phone on a carrier plan, double-check it isn't network-locked.

Install over Wi-Fi before you fly. Give it 15–30 minutes to provision.
