Banana Pi BPI-R4 4G/5G Module sim card missing in modem manager

RM520NGLAP working in BPI-R4 but it required to disable sim pin detection with at command. For reboot issue still no solution.

Alright, with qmbitat I was able to play around with AT commands (to change SIM state and to reset the card) and it needed to be explicitly enabled in modemmanager (nmcli -m any -e). However now I have an mhi_hwip0 that has sane IP addresses from my provider but I’m sending data to it but there aren’t any responses (no matter if v4 or v6). Did others see that as well? O_o
