Hello, I fail to get a PDP context for the BC92 module. Tested with both NB-IoT and GPRS priority.
Tested with SIM from 2 different providers, Vodafone M2M and Emnify.
The device register and attaches but I do not receive a PDP context (IP address).
I use this command sequence (have I missed something?).
This is the response from the modem from starting it.
