Anyone gotten latest Ubuntu Touch to work on PinePhone Pro?

Follow up: I re-imaged Ubuntu Touch, and for whatever reason, it was able to register the SIM on the network. It was also able to start a call (dialing out), but it would fail every time before the receiving phone rang even once.

I checked the APN setting and set the cellular mode to 2G/3G/4G. I could not turn on 4G VoLTE (it wouldn't let me--permanently greyed out--but this is no surprise).

I gave up and tried two different PostmarketOS images, the one with sxmo and another with Plasma. Both were able to register the SIM and make calls, AND the audio was acceptable (unlike Mobian bookworm, which did have call audio but awful quality, and unlike Mobian trixie, which had zero call audio at all).

I am going to stick with PostmarketOS for a bit. I really liked the sxmo version but it is a bit hard to operate with the text being so small.

So, unless someone posts here that they got Ubuntu Touch working and how to do it, I'll give up on Ubuntu Touch for now. Too bad--I really like the interface!

can you give a comparison of battery % burn per 10 min on each OS/distro you mentioned?
I find mobian trixie burns about 10-15% per 10 min on the pinephone pro when in active use.
I use my PPp as a daily phone but unless I have it in suspend mode I need to be plugged in, even listening to an audiobook burns most of a full battery in an hour even with the screen blank/dark.

Good idea! I haven't been measuring so far (been focused only on testing call audio functionality). I'll start paying attention now.
I do remember that Mobian bookworm's battery life was pretty good overall (I was running it for months, it would last at most 5 hours on a full charge on a pretty new battery, just walking around with it asleep in my pocket, browsing the web at the coffee shop while waiting in line). I did not stick with trixie long enough to note the battery life or burn rate. Mobian bookworm was not capable of running more than an hour if I was downloading tons of updates on Wifi and keeping the display lit. For that I had to bring along a USB power bank to assist.

Note that I have been using stock Quectel firmwares the whole time, so I could have gotten better battery life with Biktorgj's custom firmware with its lower modem clock rate.

Also, note that battery life can vary wildly based on cellular signal strength. If you spend most of your time in an area where the cell signal is poor, it will chew up your battery super-fast. In my city, signal strength is good until one crosses a particular street, and then it drops down to 1 bar. Keeping any phone battery going a long time in the poor signal area is difficult, especially during a call.

I am currently running PostmarketOS with SXMO-de-Sway, and it seems to have better battery life than Mobian bookworm did, but that's only my impression--I'm not measuring/timing yet.
