Is your phone ready?

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

  • iPhone XS or newer
    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.
  • Wi-Fi at install
    Install over Wi-Fi before you fly. Give it 15–30 minutes to provision.
