Sorry for the noise. I found this, but not all commands are implemented.
I'll try it later :)

AT+CREG=2   ; needed to make cgreg? show more info
AT+CGREG?
AT+COPS?    ; +COPS: 0,0,"vodafone UK"
AT+CSQ?     ; Returns the Signal strength value Greater than 15 is GOOd and 10-15 is accepted.
AT+CGSN     ; Return the SIM ID. if Error 22 then not found in EEPROM

On some siemens phones it is possible to:
