Connected to LTE with Twilio SuperSIM


I can connect to LTE with the iBasis SIM that came with the nRF9160DK but have been unable to connect with any other SIM.

Here is what happens in the LTE Link Monitor when I reset the DK with a Twilio SuperSIM inserted:

I checked the APN afterwards to see if it was getting that but it looks like it is not. The APN has been given to me as just "super."

How can I troubleshoot this inability to connect to LTE?
