Cisco 819g-4g not connect to service provider

[tikshoret]

Hi 

I have cisco 819g-4g when i install sim 4g and config the apn it didnt connect to the service provider 

If i take the same sim and config on asr1000 with the same configuration  its works 

What can be the problem?

The 819g come with modem sierra mc77100

Thanks

Hello,

try and power cycle the modem:

Router#conf t
Router(config)#service internal
Router#test cellular 0 modem-power-cycle

[tikshoret]

this commands not support on this router

[Georg Pauwen]

Hello,

'service internal' is a hidden command, just type it in config mode and press <ENTER>...

[johnd2310]

Hi,

I have seen issue with those routers where they do not connect when upgraded to newer ios. Try downgrading to 15.2

Thanks

John

[tikshoret]

still not working...i try another sim for diffrent service provider its work..

i try to contact my service provider not luck

[Wizard4777]

this means that the apn settings on the router match that of the second provider. find out the apn of the first provider and configure it then have it attached to the controller.

[MHM Cisco World]

Check Cisco Recommend Config, 
>>>>chat-script lte<<<<< this important 

[tikshoret]

i think the problem that the modem mc7710 doest support the  frequencies of my service provider
