LTE Router not getting IP after update.

[KGrev]

Hi, we recently changed the configuration and updated IOS on some IR809G routers we haven't used in a long time. Before any changes they would connect fine but after everything we did they will no longer automatically get an ip on its Cellular 0 interface. Pretty sure we have done something wrong but from looking through the configuration files we are unsure what we did.

I attached a new and old config file. Any help is greatly appreciated.

I would suggest to compare config, looks like some config missing working vs not working, so add that and check ?

Solved my issue. I hadnt set up the dailer settings.
