Interesting.  I can't remember where I got that one from; reading the ETSI
spec (3GPP TS27.007), it appears that I ought to be using the AT+COPS
command (which has different syntax and seems to be slightly less
flexible).

Which card do you have?


I'll send you in private mail a copy of the ETSI spec that I downloaded
last year; you might like to check if there's a more recent version.  This
version has a title of:


   3rd Generation Partnership Project;
   Technical Specification Group Terminals;
   AT command set for User Equipment (UE)
   (Release 6)

   3GPP TS 27.007 V6.4.0 (2003-09)
