Great to hear that you got it working!

Hi Didrik,

After exhaustive tests I found the problem.

I changed the command AT + CGDCONT = 1, "IP", "nbiot" to AT + CGDCONT = 0, "IP", "nbiot".

When I changed CID = 1 to CID = 0, the modem connected to the network instantly.

Regards,

Haroldo

Hi Didrik,

Yes, it supports NB-IoT network. Anyway, I will contact the provider to check for any problems at the service station.

As soon as I have an answer, I'll let you know.

Best Regards,

Haroldo

Hi.

EMM cause 15 is "EPS services not allowed in this PLMN". Are you certain that your SIM card/subscription supports NB-IoT/that network?

Best regards,

Didrik
