nRF9160 AT&T Test SIMs

[Jack Panetta]

Hey,

So I recently got some test SIMs from AT&T to use for our development. I'm trying to get them working with my nRF9160 dev kit but can't seem to get a connection to LTE.

AT&T requires me to configure my APN to "m2m.com.attz". So I'm running this AT Command:

AT+CGDCONT=1,"IPV4V6","m2m.com.attz"

When I run the link monitor and call the AT commands "AT+CFUN?" and press the "Search networks" buttons this is what it shows:

As you can see, its showing the network as "Verizon Wireless", however, the APN is configured for AT&T. Is there different configuration I need to do for AT&T?

Hi Jack,

There is also something that you should be aware of.

If you are trying to configure the default PDN connection then you should set the CID 0.

Because you have configured the context #1 (CID1), but I think you should rather configure the CID 0.

Instead of:

AT+CGDCONT=1,"IPV4V6","m2m.com.attz" 

use the following:

AT+CGDCONT=0,"IPV4V6","m2m.com.attz"
