Seeing no WWAN adapter or No SIM

[jcun4128]

This worked a few weeks ago. I have a KDE Pinephone that is now running Mobian and Phosh.
I have T-mobile sim card and I have used it before to make calls/send some text messages.
Now it will not work...

I have tried toggling the physical switch for the modem, ran a modem reset command, some other command systemctl eg5-....

Still nothing with the modem. Not sure what's wrong.

The phone is fully charged now but it has drained before.

Any thoughts/things I can try?

I don't know if it's a software or hardware problem.

My sim card is a nano type but it came wrapped in a regular sized sim adapter/I haven't punched it out/how I used it before when it was working.

WiFi and Bluetooth are both working normally as far as I'm aware, haven't done anything physical to the phone i.e. it just sits on my desk.

The distributions can be quite unstable and start having problems after some time, Manjaro Plasma in spite of its problem works every time.

If you can see the modem with the `lsusb`(if it is installed) command, you can send AT commands and the ModemManager can talk to the modem(try the `mmcli` coommand), then the problem is with the distribution, try re-installing the latest Manjaro Plasma from here

and configure the internet as I show here,

If you can not detect the modem with the above commands then it is either dead or it's firmware got corrupted somehow.

Just commenting on this. It seems battery level matters. It helps to use the original charger/wire (sounds like superstition).

Also to tap the bars in case it's disabled/will re-enable.
