Installed latest drivers. Modem detection in Device Manager works OK. It does see the SIM installed. But I cannot add an APN to it:
Are you using the TMO version of FW?
I guess it has been set by default…
You can check in AT command port AT+CGDCONT?
I tried both Generic and T-Mobile firmwares with the same result.
did you check AT+CGDCONT?
Did you check AT!GSTATUS? and see if the module can register network?
The module is registered to the network.
+CGDCONT: 1,“IPV4V6”,“”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
!GSTATUS:

by default, it should have the following:
