Hi,
We have a issue with the 3G connection (router CGR2010). We have a module GRWIC-4G-LTE-G installed in the router with a Telcel´s SIM (México). The internet provider tell us that they don’t use authentication and the APN is internet.itelcel.com.
We have created a profile with this information and a chat-script:
chat-script lte "" "AT!CALL1" TIMEOUT 60
We have the following configuration also:
interface Cellular0/3/0
ip address negotiated
encapsulation slip
dialer in-band
dialer string lte
dialer-group 1
async mode interactive
!
….
!
access-list 1 permit any
dialer-list 1 protocol ip list 1
!
…
!
!
line 0/3/0
script dialer lte
modem InOut
no exec
transport input all
transport output all
!
..
!
scheduler allocate 20000 1000
event manager applet keepalive-3G
event timer cron name CHRON cron-entry "*/2 * * * *"
action 1.0 cli command "enable"
action 1.1 cli command "ping 8.8.4.4"
!
But the interface doesn’t get the IP from the provider:
GigabitEthernet0/0 10.10.198.198 YES NVRAM up up
GigabitEthernet0/1 10.10.198.145 YES NVRAM up up
Cellular0/3/0 unassigned YES IPCP up up
Cellular0/3/1 unassigned YES unset down down
Cellular0/3/2 unassigned YES unset down down
Cellular0/3/3 unassigned YES unset down down
Tunnel1 10.10.246.126 YES NVRAM up up
Tunnel3 10.10.246.10 YES NVRAM up up
Tunnel4 10.10.246.6 YES NVRAM up up
Tunnel7 10.10.246.137 YES manual up down
Tunnel8 10.10.246.141 YES manual up down
I have done a debut chat and debug dialer, and when we do ping to a IP of Internet (8.8.4.4) we have the following result:
*Dec 27 10:32:47.564: Ce0/3/0 DDR: place call
*Dec 27 10:32:47.564: Ce0/3/0 DDR: Dialing cause ip (s=10.10.198.198, d=8.8.4.4)

*Dec 27 10:32:47.568: CHAT0/3/0: Chat script lte finished, status = Success
*Dec 27 10:32:49.416: Ce0/3/0 DDR: disconnecting call....
Success rate is 0 percent (0/5)
Please could you help me to find the problem??
Thanks.
