Cellular Phone Forum / General / GSM / April 2004SIM phone number
Hi, Is there a way to retreive the phone number of a SIM card using AT commands ? The closest I can find to retreiving some kind of ID is AT^SCID, which is some kind of subscriber number. I'm starting to think that maybe the phone number is not actually on the SIM card itself, but instead the network marries up the SCID with the phone number. Can anyone help ? Cheers, Mark. -- Hi Mark, The Phone number MSIDSN isn?t in the phone or SIM. The SIM have two numbers IMSI & Ki that authentificate the SIM (with A3/A8) in the operator network. The operator search the number by IMSI. You can?t know the number by AT commands....

This is not true in all cases. You can also send AT APDU commands by AT+CSIM.

You could have a look using AT+CPBS="ON" and then AT+CPBR=1,x Regards Peter > Hi, > Is there a way to retreive the phone number of a SIM card using AT commands [quoted text clipped - 9 lines] > Mark. > -- Correct, the phone number is NOT on the SIM card, so there's no way you can retrieve it. The IMSI number is what is on the card, and the network "assigns" that to the phone number they give you. That's why you can get them to do such as I did recently when my PAYG phone was nicked. I bought a new PAYG SIM with a new number, put it in another phone, then asked the network to assign my old phone number to the new SIM. Thus, new SIM but with my old number.
