Hello,

I think your problem might be here:

Profile 1 = INACTIVE*

--------
PDP Type = IPv4
Access Point Name (APN) = abcdef
Authentication = CHAP
Username: abcdef
Password: abcdef

!
chat-script gsm "" "AT!SCACT=1,1" TIMEOUT 60 "OK"
!
interface Cellular0
 ip address negotiated
 encapsulation slip
 dialer in-band
 dialer idle-timeout 0
 dialer string gsm
 dialer-group 1
 async mode interactive
!

Make sure that the resalted information its correct, the profile config it´s wrong. Also check the chat-script, not all chat-scripts works for all carriers, the encapsulation too.

And i think that you should add a route for the cellular interface. Something like "ip route 0.0.0.0 0.0.0.0 Cellular 0 200" if you want to use it as backup.

Regards.

Hi Carlos,

You are right I changed the static route to 0.0.0.0 0.0.0.0 cellular0 and run a ping and the profile came UP. It means that the chat script and the profile is ok.

The issue now is that after the router reboot I need to run a ping from the router first before the profile get activated.

How can I bypass that process!!!

Thanks

No problem :)

Maybe you can use keep alive or ipsla

Hi Carlos,

Neither keep alive or ipsla help me. 

Need your urgnet help ….
My Sim is activated for very short time,but most of the time its always INACTIVE.

Sry about the delay! the profile goes inactive due to lack of traffic. Try making a ping with source (use the vlan, interface that uses the cellular interface as output) and you will see that the profile goes active again.
