Yes, I am in the U.S. Sailfish has been available for the Pines early on. Most of the time I was on T-Mobile and later Mint Mobile. Calls worked fine I remember. VoLTE wasn’t being forced yet so maybe that’s why.
Regarding non-user-servicable battery, I have a ZTE Axon 7 that was in need of a new battery. I have the batteries and included tools but I lamented the task of prying open the case. Laziness and procrastination turned into weeks, then months, and sad to say, years. One of these days. :D
I actually have a third Pinephone. The one that came with Ubuntu Touch way back when. It had that faulty USB thing. I got an updated mainboard (more RAM and EMMC) but never got around to swapping it in. Another one of these days.
With everything that’s been going on with Android I really do want a Linux that can be a daily driver. Just need to put in more effort. I keep throwing them aside for weeks at a time.




Been using Thexyz for a long time but another I also use that has so far been reliable and inexpensive is Cheap email for everyone | Purelymail. Also use it with my own domain. See if they fit your criteria.
EDIT: Oops. forgot about the EU requirement. Maybe nevermind.
