Hi Mkt,
I agree with you. Can u provide any supporting document to support. I found in GSM spec. release 02.07 and GSM 11.11 . In that it has mentioned that the name of the operator is defined in SIM. But in case of roaming, what could be the exact condition. If it is in SIM, is it possible to burn the list of world mobile operator names in each SIM during its manufacturing procedure. Kindly clarify
