Cisco 881G 3G config

Heya, the 3G modules have a separate control module you will need to configure the relevant APN settings on before you should add the config on the router. Its been a while since I configured my 887 for 3G backup. To configure the modem do the following:

Cisco documentation: cellular <slot/wic/port> gsm profile create <profile number> <apn> <authentication> <username> <password>
Therefore you will need your ISP's APN settings to set this up. Most SA ISP's does not have any username or password configured, so the following worked for me (as far as I can remember).

Therefore to configure mine (Axxess SIM) I had to do the following:

!
cellular 0 gsm profile create gsm axxess
!
conf t
!
chat-script gsm "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
!
interface Cellular0
description GSM 3G
ip address negotiated
ip flow ingress
ip nat outside
encapsulation slip
dialer in-band
dialer idle-timeout 0
dialer string gsm
dialer-group 2
async mode interactive
!
ip nat inside source list 5 interface Cellular0 overload
ip route 0.0.0.0 0.0.0.0 Cellular0
!
dialer-list 2 protocol ip permit
!
end
!
