      Using Gpy with expansion board 3. I was able to setup and connect using AT&T iot sim using:

      # While the configuration of the CGDCONT register survives resets,
      # the other configurations don't. So just set them all up every time.
      print("Configuring LTE ", end='')
      lte.send_at_cmd('AT+CGDCONT=1,"IP","m2m.com.attz"')
      print(".", end='')
      lte.send_at_cmd('AT!="RRC::addscanfreq band=17 dl-earfcn=5780"')
      print(".", end='')
      lte.send_at_cmd('AT+CFUN=1')
      print(" OK")
      

      Then registered the device through pybytes and did an integration azure.
      Now the device does not connect. re installed firmware for modem and gpy.

      Any suggestions?

        @irfan5911 figured it out. correct band and earfcn are crucial.
