PLS62-W Network Registration denied | Telit Cinterion IoT Developer Community

December 16, 2022 - 3:41pm, 132 views

I'm in the UK using an O2 data only SIM which I tested as working today in a phone. I can see networks OK:

+COPS: (1,"O2 - UK","O2 - UK","23410",7),(1,"O2 - UK","O2 - UK","23410",2),(1,"vodafone UK","voda UK","23415",2),(1,"O2 - UK","O2 - UK","23410",0),(1,"vodafone UK","voda UK","23415",7),(1,"vodafone UK","voda UK","23415",0)

I have a CID setup correctly(?)

+CGDCONT: 1,"IP","","",0,0


but when I try to connect I get this error:

+CEER: "SM deactivation",136,"Regular PDP context deactivation"


CREG cycles between 1 and 3 and CEREG cycles 0,2 then 3 meaning (?) registration denied.

As I say, the SIM works in a phone so I'm clearly doing something wrong. Any help would be greatly appreciated!
