BG95-M3 no connectivity on LTE B1/B3 and GSM DCS1800

Hi!

I have a couple of BG95-M3 modems. I’m only able to get connectivity on LTE/NB-IoT B20 and GSM EGSM900. If I i.e change the list of bands with AT+QCFG=“band” to B1, B3 for eMTC and NB-IoT and DCS1800 for GSM I get no service. I also have a EG915U modem. This modem has no problem and can “see” all bands. I have used the same antenna and sim card in my tests.

Are there any known issues with BG95-M3 and the bands I’m having issues with?

Guess I found the reason. BG95-M3 is CAT M1. Looks like the only band for this in my location is B20.
