Hi,

Sim: Vodafone Italy enabled for NB-IOT.

This is the procedure I follow:

AT+QSCLK=0
ATE1
AT+CSCON=1
AT+QBAND=1,20
AT+CFUN=0
AT+QCGDEFCONT="IP","m2m.vodafone.it"
AT+QRST=1
AT+QSCLK=0
ATE1
AT+CSCON=1

This is the result:

F1: 0000 0000

V0: 0000 0000 [0001]

00: 0006 000C

01: 0000 0000

As you can see it keep getting denied.
If I put the sim in a phone it works with the apn “m2m.vodafone.it” so I don’t know what to try.
