Hi there i have Sodaq Sara r412 and for whetever reason i cant get it to connect to the network.

I have uploaded the passthrough sketch and can communicate to the modem but the list of at commands just returns errors.
I am also trying with m-center from ublox and i get the same errors.

AT+URAT=8

+CME ERROR: Operation not supported

The following command:AT+USIMSTAT? return a 4 which is sim not active?

Any advice would be appreciated
