LTE M1 with Swisscom SIM

  • Is anyone using LTE M1 using Swisscom SIM? My lte.attach() function is not working. Always returns False for lte.isattached().
    I am trying through REPL with manual commands.

    >>> lte.send_at_cmd('AT+COPS=?')
    '\r\n+COPS: (1,"22801","22801","22801",7),,(0,1,2,3,4),(0,1,2)\r\n\r\nOK\r\n\r\n+CEREG: 4\r\n'

    The result of above command shows that Swisscom coverage is there. '22801' is the PLMN code for Swisscom.

    Has anyone had success with just lte.attach() with Swisscom SIM?

    If anyone is using Swisscom SIM for LTE M1, could you tell how you are connecting it? (any custom apn name or something)?
