Device can't/wont connect to t-mobile


  • 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.

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

    Any advice would be appreciated
