Cisco Employee

Hello All , 

I have a Cisco 829 router , trying to configure for 3g and 4g , i am unable to get the cellular interface up , the same sim card works fine on cisco 877 router , i believe there should be some configurational changes to be made 

I have enabled debug logs 

debug modem 

debug chat 

debug dialer 

debug cellular 0 messages call control 

Can anybody help me understand the debugs 

Also if you have any documents to understand the debug logs and dm logs , kindly share 

Any help will be greatly appreciated !!

i had the same issue.

watch your line configuration. 

line 3

dialer script gsm 

i had to change it for  dialer script lte 

i have been working with a 819 router last days, copy your  running config and  may be i can help you.

Thank you for the response , i was able to figure out the root cause 

What was your resolution? I have the correct scripts, dialer and config, but still flaps on Cell 0
