Howdy,
Just purchased 10 x Cisco 4331 router with dual 4G LTE AT&T and Verizon NIM modules, and have modeled the configuration off other Cisco routers (2901 with first gen NIM modules) that have air cards installed. I am having a pretty tough time getting the air cards to acquire an IP address. They are registered with both carriers and are pulling LTE service and a cellular number. The new 4K router cellular config will not let me enter "dialer string lte". I have put all the configuration I can think of to help with the resolution.
The configuration of the AT&T aircard is
