Troubleshooting incoming SMS/MMS
I have a new PinePhone 1.2b with the stock Manjaro + Plasma Mobile, and one of the first things I tried (after phone calls!) was text messaging in Spacebar. It worked fine for sending a text, but a simple plaintext reply never showed up on the PinePhone.
I see some old threads and mentions elsewhere about troubleshooting this with ModemManger and mmcli, but ModemManager is mysteriously not running for me. Have times changed and there's some other way I should be investigating this, or is it unexpected that ModemManger isn't running? I've flailed around and tried to get it going (see below) but maybe I'm barking up the wrong tree.
