We are investigating migrating from ISDN to 3G/UMTS access for a couple of remote sites and think the 3G-WIC will be a good substitute. According to the documentation you have to authenticate to the service provider through PPP to get IP-access. This seems straightforward and IOS standard. What we not have found in the documentation is how to enter the PIN-code of the SIM-card, which remains locked without a PIN-code, and will not register in the umts-network.
Is there anyone having practical experience of unlocking SIM-cards on the 3G-WIC? Is there a IOS command for this?
