Does your phone support an eSIM?
Dial *#06# on your keypad. If the panel that opens lists an EID, your phone is eSIM-ready. It works on iPhone and Android, takes about ten seconds, and nothing leaves your device.
- Open the Phone appThe normal dialler — the one you make calls from.
- Type *#06#No need to press call — the panel opens on its own.
- Look for EIDA 32-digit number under the IMEIs. If it is there, you are eSIM-ready.
No EID? The phone takes a physical SIM only, and a travel eSIM will not work on it. If the EID is there but your handset came from a carrier, check it is not network-locked before you buy.
