iBasis SIM, on the other hand, registers perfectly via KPN band 20. So I can conclude that the radio is working.

I’m using nrf9160-DK (devkit), but it should work the same as nordic thingy:91.

Strangely, now it started working without any change - connected right up after enabling the modem.

iBasis SIM, on the other hand, registers perfectly via KPN band 20. So I can conclude that the radio is working.

I’m using nrf9160-DK (devkit), but it should work the same as nordic thingy:91.

I’m trying to connect using the iotcreators LTE-M SIM, but it seems like network registration is being denied.
+CEREG: 2,"55F4","0186EB01",7,0,19
I did register the ICCID in the portal days ago already, do I need to do anything else? Has anyone been successful in registering with LTE-M in the Netherlands?
