How to verify eSIM support on your device

- Android: Settings → Connections (or Network & Internet) → SIM Cards → look for "Download a SIM instead" or "Add eSIM".
- EID check: most eSIM-capable Android phones show EID in Settings → About Phone → Status.
Tip: Even if your phone supports eSIM hardware, it must be unlocked (not carrier-locked) to use third-party eSIMs like Cellesim. Most phones bought outright are unlocked; phones from carrier instalment plans may require unlocking after the contract is paid off.

Compatible models include iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, plus a growing list of mid-range devices. If your phone has Settings → Cellular → "Add eSIM", you're ready to use a Cellesim plan abroad.
