So I tried Tedit but it wouldn't display the contents of the plaintext document. I also exported my db to a csv file but sorting through that garbled mess was going to be a chore. I then remembered that there was a Bitwarden app so I downloaded that but it no longer works as of last year according to Github issues. I next tried to load the Bitwarden website but Morph and uWolf wouldn't display the page. I then finally found a way. I created a note with the logins I needed on Nextcloud and synced Jotit Cloud Notes with my account which brought the note down so I could copy and paste the data. A happy ending. Still better than typing out multiple 40 character passwords manually.

@Simmonz Can be worth playing around a bit with APN settings for MMS. I needed two separate APNs for Internet and MMS. I was able to use a tethering APN for my Internet and the nornal one fot MMS. Some seem to need this, others have found the opposite, that it only works with combined Internet and MMS on oneAPN setting. I still lose about 1 in 10 of incoming MMS messages, but at least I get a notification. If you're able to test VoLTE, I'd be very interested. I believe it should have a VoLTE icon in your indicator bar at top when connected on a call if it's working properly. Insights on call quality, and whether SMS works normally with VoLTE enabled also welcome. Too bad about reception. Not sure why it would be worse with same device on UT vs Volla OS. Thanks for the info!

@Simmonz similar behavior, but different cause I guess.
