How it works

How A-Sim works

Every A-Sim eSIM is pre-provisioned with local carrier profiles for your destination. When you land, your phone attaches to the strongest nearby 4G/5G partner network — same speeds as a local SIM, no roaming charges, no physical SIM swap.

Pick & pay

Choose a country and a plan. Pay with Apple Pay, Google Pay, or card.

Install in one tap

On Android, tap your install link. On iOS, scan the QR — and keep Wi-Fi on for 15–30 minutes after installing so your phone can activate the line.

Land & connect

Your eSIM waits until you land, then auto-attaches to the strongest local 4G/5G partner network. No setup, no roaming fees.

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.
