      Has anyone been able to get NBIOT working with AT&T in the US?

      What APN did you use?

      What band did you use?

      Thanks

        We've tried multiple options with no luck attaching to the AT&T network using the current GPy NBIOT modem firmware using an AT&T SIM provisioned for NBIOT communication.

        We've tried bands 2, 4, 12, and also not specifying a band. It's our understanding that the APN to use is the same as what we use for CAT-M1 (10569.mcs).

        Other than specifying the band in the attach command, are there any other differences between using CAT-M1 and NBIOT?
