I have TER-GN910 embedded in a data logger located in Asia. The modem has a local SIM card. The application responds to commands sent via SMS and the modem app responds with the requested data. I have recently sent SMS commands and found that the phone number displayed on my phone is not the same as the phone number I used to send the SMS. The phone number displayed on my phone happens to have a UK code. Can anyone explain why this is.
