Instarem’s eSIMs (currently available only in our Singapore app) are compatible with most smartphones released 2018 onwards. But this may vary based on your phone model and region. You can check and confirm with your phone manufacturer – or review the full list of supported devices here.
Also, your phone needs to be carrier-unlocked to use Instarem’s eSIM. If you bought the phone without any contract with a mobile provider, it is likely already unlocked.
