We are testing our BG95-M3 module with NB-IoT networks but it seems that we cannot get it connected with T-Mobile. According to T-Mobile’s certification page, BG95-M3 is on the certified list, but our module have a different TAC (86420005), which is not listed on the page. We guess this might be an issue.
We are wondering if it is the real reason or there is something that we are missing. Also, if it is possible for the device to use T-Mobile’s NB-IoT network. Thanks!
