Hi Viorel
Based on your test command finding that you failed to register a network, you can check if your USIM supports CAT networks and if the EMTC counterpart BAND is reasonable.

Thank you, @tabor.tang-Q

Based on your information I’ve switched on EDGE and I have put the General APN, not the one especially for M2M. There I have seen that the module gets its registration. I’m happy the the BG95 is OK, I was afraid of a problem on the HW board.

I’ll see what I can do with the SIM.
