Please confirm whether the device is locked by the telecom operator before purchasing.
Please check if your device supports eSIM for it to function properly. To check, dial *#06# on your phone's dial pad. Displaying the EID number indicates your device supports eSIM; if no EID is displayed, your device cannot use eSIM.
If you cannot connect to the internet after activating your eSIM upon arrival, please manually enter the APN: m3-world (it will switch automatically under normal circumstances).
