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

Hope to help

Hello Leepeiwai,
this is fine
have you configured the chat script?
be aware that the string that follows the ATDT command is specific of the provider
Hope to help

yes, chat script is applied. configuration as below:
chat-script NextG "" "ATDT*98*1#" TIMEOUT 60 "CONNECT"
interface Cellular0/0/0
no ip address
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer in-band
dialer pool-member 1
async mode interactive
!
interface Dialer0
ip address negotiated
encapsulation ppp
dialer pool 1
dialer idle-timeout 0
dialer string NextG
dialer persistent
dialer-group 1

I am able to connect and get an ip address from the Service Provider by changing the SIM card.
This time, unlike the previous SIM, the CHV1 code of this new SIM is disabled.
router#show cellular 0/0/0 security
Modem Security Information
==========================
Card Holder Verification (CHV1) = Disabled
SIM Status = OK
SIM User Operation Required = None
Number of Retries remaining = 3
I this that is why I could not connect to the Service provider.

hey,
make sure of the below configurations:
1- chat script.
2- profile creation.
3- correct natting.
4- GSM or 3G coverage and configurations.
5- cellular interface ip address should be negotiated.
as well try to change the script to
chat-script NextG "" "ATDT*99*1#" TIMEOUT 60 "CONNECT"
i've never used a dialer config for GSM, i configure the cell interface directly as below:
interface Cellular0/0/0
ip address negotiated
ip nat outside
ip virtual-reassembly
encapsulation ppp
no ip mroute-cache
dialer in-band
dialer idle-timeout 0
dialer string ISP
dialer-group 1
async mode interactive
ppp chap hostname ISP
ppp chap password 7 ISP
