@rik I tried all of the above. There was no change. With wireless on and in 4G, I can send but not receive. With wireless off, reboot, and in 4G, send but not receive. Same with 3G. I am going to try and pick up a Red Pocket SIM on the way home and try that, will report. Looks like AT&T is the only game in town where I am.
I got MMS working (send and receive) on US Mobile (T-Mobile network) in the USA but only after booting the phone with wifi disabled. Once wifi is enabled, then SMS receive and all of MMS breaks. Here is where I wrote up a bit more detail: https://forums.ubports.com/topic/6369/tmobile-issues/17
Note that with the same SIM on a N5 I don't have any SMS or MMS issues, so it seems specific to the Pixel 3a
Well, I still have SMS receive and MMS send / receive not working reliably. Sometimes / often the messages will come after a reboot, and I still don't think I have ever gotten messages when wifi is active, but since there are other unreliable pieces here it may be coincidence that I got it working only with wifi off before. In short, I am still confused and more testing / debugging needed. Any pointers on where to find logs about what may be going on? Power saving maybe killing messaging service???
Can anyone NOT in the USA confirm that the Pixel 3a can receive SMS when wifi is on, or that can send / receive MMS? Trying to understand if this is a US carrier thing (see above link to Tmobile thread) or if it is this phone across the board regardless of carrier? Maybe @fredldotme could comment on the state of SMS receive and MMS s/r?
I guess it was the carrier, Patriot is a "third party" and has limitations according to their support line, it never connected, and we tried for an hour, but the phone did not report a message to indicate it was SIM locked, I got an AT@T prepaid and it works great...basically same low rate too. I had reflashed to android and upgraded to Android 11 verified it worked, then flashed UT which was successful the very first try. A lot works on the Pixel too.
I have a Pixel 3a XL and using GrapheneOS, which the updates end in August 2022. At that time, I will be installing Ubuntu Touch so I am watching this page for any updates regarding a smooth installation. Thanks
@crab_aesthetics First I thank you for the process you showed in your install. It is a good road map. I will be trying a similar install as soon as I get my replacement phone. I will be using a Linux laptop and my cellular provider is Visible by Verizon.
On my pixel 3a I am able to use GPS, although it is slow to connect. It is my understanding that only gps hardware is used, so it does not get the "head start" provided by approximate location from cell tower settings.
-Set "lock when idle" to "never" from system settings/ battery. (I think GPS is shut down when locked)
-Run "sensor status" app from Open Store
-Select GPS, mine shows "found supported backend", and "active"
-wait until you get a location. This could be several (10?) minutes, although mine is usually faster.
-Try your map software
Once you verify functionality, you can probably skip a lot of this.
@applee thanks. I didn't want to flag him with the use of his handle (I think he has a few other issues he is tackling at the moment) which is why I simply added his forum user page if we wanted to escalate the issue. Regardless, glad to hear he is aware. Cheers
