Hi,

We are trying to register our BG95-M3 with an international profile.
Unfortunately, we are constantly getting a Registration Denied error: +CREG: 3.

Vodafone indicates that the SIM card never even attempted to register or had a session with them, but the SIM card is activated and provisioned.

Are we using the AT commands wrong?

#2

We use the following AT commands to connect to the vodaphone uk NB-IoT network.

AT+CFUN=0 //Turn modem off
AT+CGDCONT=1,"IP","lpwa.vodafone.iot"
AT+CFUN=1 //Turn modem on

AT+CEREG? //Poll until response equals 0,5 or 0,1 - EPS connection (LTE Connection)
