MKR NB 1500 on T-Mobile IoT working for reals?

Hey all:

Might be a stupid question, but I have a working design on the Twilio NB dev board that I was trying to move to a base MKR board, but even the example code doesn't work. I can take a working SIM from my dev board, move to the 1500 and try to run a sample like NBScanNetworks and I can see the CEREG response go from 2 (search) to 0 (not registered).

My guess is that the radio isn't compatible or this board is bad. :expressionless: Which sucks - I see other people are using the AT&T network. Anyone using T-Mobile NB? I can just order a AT&T SIM but I don't want to twiddle my thumbs for a week if this is just a bad board for nothing. :slight_smile:

Answer indirectly is 'nope'. The portal that sells the TMobile cards has been updated to say only the Wio platform is supported, so I got a paperweight now. Whee. :-\
