3G-WIC and SIM-card

Unanswered Question
Jun 19th, 2007

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?

Assuming this is purely for SIM access it would be expected to leave the SIM unlocked whilst in the HWIC installed in the router. Physically securing the host router would be one option. I have not seen SIM PIN features documented. The network operators can also offer either managed (via a hosted AAA server) or proxied (to your AAA server) for SIM authentication.

Do you have your 3G-WIC already up and running? Im interested in this solution, too but can't even find the datasheet for this product on cco...

thanx, i've just found it using the search-string "Hwic 3g" :-)

Can you tell me, if there is an antenna included? The Dynamic-Configuration-Tool doesn't worry about configuring it without antenna-option!?

it's correct, that the "Dipole Omnidirectional " is included? (This is the default antenna. Multiband faceplate mounted dipole antenna. This antenna is included with all faceplate-mounted 3G wireless WAN HWICs.)

Once the SIM is unlocked does it need to re-unlocked each time the router is reloaded?

Look for the 860, 880 and the 890 ISRs. An autonomous/lightweight AP is an option.
