Oneplus n10 24.04-2.x follow up
-
@undrwater HI, Could you read my (wrongly addressed) reply to vverve, asking about your use of Nord N10 in USA, and actually using VoLTE ?
Also, I am often in rural area, and mostly use WiFi calling (which, from what I understand, shares code with VoLTE).
Have you tried WiFi calling ?
Any other info or suggestions, before I try to return recent Pixel 3A XL and buy a Nord N10 ? -
@undrwater Which exact model of Nord N10 do you have ?
Was it already Factory / Bootloader unlocked, or did you have to go through the Oneplus/T-Mobile bootloader unlock process ? [The Pixel 3A XL I recently bought to install UT on was factory unlocked, and easy install (had to change A12 back to A9, but G Chrome based tool worked very well)].
Also, one of the pages I found lists international version & another in one group, but a separate group - labelled - 'Unsupported' for Nord N10 T-Mobile and N100 Metro-T-Mobile - with slightly different original versions of firmware listed for recovery to OEM.
Searching Ebay for BE2026 (North American Factory Unlocked) or BE2029 (international) produced zero results. Searching for 'Factory Unlocked' produced inconsistent results, wherein they repeated 'Carrier Unlocked' next to both Unlock Status, and Carrier Status. Only one listing said 'Factory Unlocked' IN the listing (was highest $$).
I would appreciate any suggestions from anyone who has had success with this. -
@oldbutndy I don't totally understand all the N10 versions (and I really tried at one point!) but Ruben, the porter/maintainer, has said that the T-Mobile / Metro versions should work, despite what the device page says. You'll find at least one other post in the N10 section of the forum that shows someone using an N10 Metro, in USA, who now has VoLTE.
I think no one wants to guaratee it, as it's not what the porter uses, but it sounds like it'll work.I think Factory Unlocked generally just means it was never locked to a carrier, but doesn't mean bootloader is unlocked.
I found downgrading android, after unlocking the bootloader, to be a pain on the N10, but I'm pretty novice at that sorta stuff, and I got it done in the end.
Seek instructions, get the MSM tool, understand EDL mode. You'll figure it out!
Good luck! -
BE2025 Metro - 1 SIM slot
BE2026 US unlocked - 1 SIM slot
BE2028 T-Mobile - 2 SIM slot
BE2029 International - 2 SIM slot2025 and 2028 come factory (bootloader) locked but can be unlocked with token, or without token using the procedure in the N100 thread. See xda-developers for appropriate files.
The important thing is network unlocked. Make sure it is, or you are able to do so before purchase. Otherwise, you will be stuck to whoever's network it is locked to.
2nd SIM is irrelevant as it does not work with UT. 2029 lacks some US bands. Purchase any of the other three if in NA - NOT BE2029
Any of the other three are good as they have the same band coverage. 2026 just eliminates some hoops as it is already factory and network unlocked.

@rocket2nfinity Thank you also for quick reply & added helpful info ! Between Wally & your info, I have more confidence in the possibility of success.

I left out requirement for WiFi calling (if a phone is to be 'daily driver'), in previous posts.
I use WiFi more than cellular (basement office & workshop, in rural area = terrible cell reception).
I read that VoLTE functionality shares code with WiFi calling, so the VoLTE functionality is required.
Also looked into Linphone (failed to install native, due to 64 bit not available, also could not find a version to install via Libertine).
The UT old revision device pages for Nord N10 & Volla Phone do NOT mention WiFi calling in the main chart of Supported Features, and also NOT listed as 'Unsupported' below that - just plain missing !
On the bright side, wireless external monitor works OK on the Pixel 3A XL, and is listed as functional on the Nord N10, but as NOT functional on the Volla. (at least on old releases page).
So, if trying for a portable office, Nord N10 appears to be the better choice !
Maybe time to create a spreadsheet comparing status of features across UT supported models...
Does anyone know if a summary (all devices) status chart exists ? -
I made a chart. Added status of all phones that might support VoLTE. partially added notes on Cellular Bands (some model phone do not support all US bands, apparently). I did NOT check every single band by #.
Google AI answers mentioned Volla & Fairphone optimized for European & other countries. Pixel 3a = Halium 9 & developer has no VoLTE access to test.
Summary result is Nord N10 (or N100) = ONLY phone(s) that have functional VoLTE & support all US GSM bands.
Please correct me if I am wrong. -
@oldbutndy You are correct. The N10/N100 porter is going to try to revive the OP6/T port, so that might be number 3. But, it will be a while.

@oldbutndy VoWiFi is still being investigated.
You could put your P3a on Droidian or Mobian/PostmarketOS and use SIP. UT devs are working on SIP integration in the dialer. It partially works now, but still needs a lot of work to be functional. In the meantime, SIP support is functional on those other OSes and would be the equivalent of VoWiFi.
