Hi

I have configured cisco HWIC-3G-GSM router cellular and Dialer0 interfaces.

The WWAN LED is green solid (active, no traffic). I turned on debug chat, debug ppp negotiation, but no output generated.

I have also tried to ping to an internal network and a public ip, still no debug output.

cellular Profile status is inactive.

router#show cellular 0/0/0 security

Modem Security Information
==========================
Card Holder Verification (CHV1) = Enabled
SIM Status = OK
SIM User Operation Required = None
Number of Retries remaining = 3

Please advice.

Hello Leepeiwai,

you may need to create a modem profile before being able to use the HWIC. It is a sort or registration with mobile provider

see

Hope to help
