LTE minipcie card ec20

[Mori 0]

I inserted the ec20 module to identify that mmcli can be sent off, and nmcli can view the gsm device, but the connection process cannot be used, and mmcli shows that the sim card is invalid

hello @Mori, 

i'd suggest to use any of the modules from qvl, such as ec21-e, ec25, or uc20
