I looking for any insight anyone might have in detecting the following problems with sim card configuration (using a modem), So I can report errors
Is there any way to tell a sim card is actually allowed on the network? (AN AT command?)
Invalid context configuration, this appears to Just reject all options during the IPCP stage of the link negotiation.
Not configured to allow GPRS service, I have some sims that seems to just reject all the IPCP options.
Thanks for any help.
