@lduboeuf This has been my experience using a Oneplus N10. Since VoLTE landed, idle drain has seemed notably less pronounced. A very nice surprise, especially on a device with an aged battery.

Very nice!

Non-EU users, note that Volla will sell outside the EU via an indiegogo page linked from their main site. The Plinius page presently links to a Quintus Indiegogo page, but I'm sure one is coming for the Plinius.
Seems they've been selling internationally this way for a while. I didn't know.
Not much is written about cell network compatibility, for those of us in nations where networks may require "whitelisting" for a device to be able to make calls, etc. But I blame the networks and a lack of government oversight for this more than I'd blame a company for not going and asking cell networks all over the world to whitelist them.
Anyway, as ever, you need to do your homework as to whether the device will work on a given network. Nice to buy from a company directly supporting and working with UBports!

@Kjetil Yes, sorry UB Connect is what I'm thinking of. Wasn't sure what all features were involved.
Hope you find something that fits your use!

Hmm. Perhaps wise to post here as well:
VoLTE working on Oneplus Nord N10, 20.04 OTA-12 RC-1.
Lucky Mobile under Bell network, Canada.
SMS working as normal.
MMS working as well or perhaps better than before. Fewer undownloadable messages, though this could yet be coincidence.

@Kjetil Somebody has made a version of KDEConnect for UT recently. I'm not sure it covers all your uses, and I think it's totally unconfined, so use at your own risk, but could be worth looking into.

@Fizz Somebody might know more than me, but my impression is that it might not be wise to count on VoLTE on Pixel 3a.
And yeah, 3G has gotten pretty patchy here, hasn't it.

Cheapest option, with best network coverage, is probably Oneplus Nord N10. VoLTE is working well for me on Lucky Mobile (Bell network). It's pretty new having VoLTE on this device. Huge cudos to Ruben, the maintainer.
There area few for sale on kijiji.
Most N10s here should be ok to unlock, but sometimes one of floats up here tied to a USA network, and with those you need an unlock token from Oneplus, which people are struggling to get, depending on if you have a receipt from an "official vendor".
The BE2026 models can just be unlocked, no fuss. Downgrading android is a bit tricky, but doable.

A couple Xiaomi phones have VoLTE - Poco X3 NFC and Redmi Note 9 Pro (and related Miatoll devices), but aren't ideal for Canadan network bands. I was trying to get a Redmi Note 9 Pro working, but to unlock bootloader, Xiaomi was requiring things that involved receiving short-code SMS, and they just wouldn't come through on any Canadian network. Multiple conversations with cell carriers and Xiaomi later, still can't get it unlocked.. and network coverage turned out to be kinda bad in my area.

I've heard of people using Fairphones in Canada. But usually can't find one except from overseas and it's a lot of money when the $%£$ networks won't guarantee they'll "whitelist it" and as such allow phone calls.

Other ports are coming along, but I guess the short of it is Oneplus N10 (or also N100, which lacks 5g) is your best bet.

All working well on 20.04 OTA-12 RC 1
Tested recurrent events, working hours, all day events, and fiddled around in general. All looks good!
Thanks for all your work Lionel!

@UBportsNews Plamen, of the Brax3 team, recently said that they were actively working with "the UT team" on the Brax3 port.
I thought UBports doesn't usually maintain device ports but maybe it's different when working with device manufacurers?

Is the port maintainer Brax3? UBports? A joint effort? Or is the hope that some individual will take on the port in the long run?

Thank you all!

@libremax Wow, nice bit of news! Thanks for sharing

@idonthatevests Interesting. For what it's worth, I'm very confident that mine was glitchy before I ever installed uFirefox. I did have Ambot Installer for the more limited Lomiri toolkit, but I'm not sure whether ithas anything to do with that.
Mine always seems to glitch out after notification/SMS.

I always kinda figured something about my install was messed up, though I did install what I thought was the appropriate firmware and do the whole MSM&EDL mode thing.

I mostly ignored this issue thinking that if it only affected my phone, it's not that important. But it'd be handy if we could pin it down.

@idonthatevests Does this glitch involve the screen flickering? Does it seem to occur in conjunction with incoming notifications/messages?
I don't have solutions, just have yet to encounter anyone with the same issue as me, and this sounds similar. Only the reboot to Fastboot saves me.

@shengchieh I would agree that Oneplus N10 best matches your specifications, and that the BE2026 version is your best bet for unlocking. This is assuming you are in USA, as I don't know of anywhere else where there's any talk of sunsetting 4G.

@bgriffis Hmm.. yeah, if WiFi being off didn't fix it, it's worth considering whether it's the two APN settings vs one setting thing. Plenty of folks have had it work one way but not the other - mostly I've heard of North Americans needing two separate settings.
For me in the past, MMS only worked if I had two APN settings AND the APN & MMSC for MMS did not match the APN & MMSC used for Internet. I got around this by finding a "tethering" APN for my carrier and using that as the Internet setting, and the normal APN for my MMS.

I still do get the same message as you, "Could not fetch...", for maybe 10 or 20% of incoming MMS messages, and clicking Download only yields a second (and third, and fourth..) such message. But if the I ask the sender to resend the same file, it generally does work the second time. I have never been able to figure out why this happens.

@Bushman77 Nope! UBports Foundation does not maintain device ports. It's all done by people like you.
If you have the skills, or the desire to learn, you could be the person who brings Ubuntu Touch to this device. Otherwise, as with any device, there's no grand plan to port UT to it.

@peat_psuwit This has fixed the problem I had upon updating to OTA-11 where I stopped receiving incoming SMS, and reflashing with the installer did not fix it. Fantastic news for me, though I don't know of any others who had quite this issue.

This update also brings VoLTE and 5G to Oneplus Nord N10. I made my first VoLTE call ever in UT! I haven't stumbled into a 5G zone yet to test.
SMS, MMS, mobile data are all funtioning perfectly so far. Everything else is functioning as normal too. I'll post again if I run into any issues.

Thanks so much to everybody who worked on this!

@UTUS I second the assessment of @rocket2nfinity .
I've always found MMS a bit quirky, but largely it works except for group messages. Can vary a bit depending on provider and APN settings.
Group messages have been a known issue for 5+ years, Ibelieve there's just no fix. I receive nothing, no notification, no error, when someone sends a group message. No way to know anything was sent. I just tell my contacts I can't do group texts. It's more awkward now that iOS picked up RCS.. everyone expects group messages should work.
So far as I know, RCS is on the radar of the devs, but not really even a work in progress yet.. they do incredible work with few people, mostly unpaid.
In Canada, this is the most unusable part of UT. Otherwise it's great! Somehow even my banking works, though this isn't the case for most.

Definitely look into bootloader unlocking before buying. Surest way, as stated, is BE2026 (North American version, non-carrier specific). Most people succeed in getting an unlock token from Oneplus eventually, but they now seem to say they only send one when given proof of purchase from an official vendor or something.

Downgrading to aporopriate Android is a bit tricky.. follow the instructions, using MSM tool and EDL mode. You'll figure it out!

@libremax Wow, nice! Thanks to whoever did the work and thanks for letting me know!

@pparent Thanks for posting that article, I hadn't heard.

Low probability of success can be offset by low cost and high value of success.
I think the moment we're in presents opportunity like never before. In addition to the French government looking at digital sovereignty, the Danish government is trying to get away from American tech companies. I could imagine many other governments may be considering this.

We don't have the interoperability rules here in Canada, but I'm still going to be suggesting to my member of parliament and a couple of ministers that the government should be proactive in examining and acting on the threat posed by the fact that most members of our government, military, and general populace use privacy-intrusive smartphone OSes controlled by a couple USA-based tech companies whose CEOs have already demonstrated a willingness to comply with what increasingly demonstrates itself to be an aggressive and authoritarian government.
(I respect the forum's rules about not getting political and hope this didn't cross any lines, but I think what I said is factual and relevant to the point I'm making. I'm not taking a position here on whether annexation is cool, just trying to explain why I think there's an opportunity for UT.)

Matrix has benefited from being adopted by various governments and militaries, even if in pilot projects. The challenge is much greater with mobile OS adoption, but if the resources and the need are there, it doesn't seem impossible.
My government, for example, is suddenly trying to spend vastly more than ever before on the military and routinely falls short of its spending targets. I could make the argument that a secure, private and functional mobile OS is of strategic military importance
And I will! Opportunities like this don't always last very long.

@ChromiumOS-Guy Thanks for the response. Didn't realize the website had a repo, but I very much don't understand the world of repos yet. Sloooowly learning things
Glad the issue is raised. Don't want to badger the website team, they do plenty!

A number of times people have posted along the lines of "Why is VoLTE listed as unsupported?" While it's important not to overpromise, at this point I think the claim that "VoLTE is not suppoted" isn't informing people properly.

I'd suggest

• a rewording of the Global Issue along the lines of "VoLTE remains in the (experimental? beta?) stage, and functionality cannot be guaranteed"
• the addition of a new category under Cellular, "VoLTE", which at present could be listed as "Partia" for any devices with VoLTE abilities and "Not Working" for the rest.
  -perhaps also considering 5G at the same time?

Maybe if people think this change is a good idea we could help the website folks with wording and with which devices should be listed as Partial.
Open to thoughts. Many thanks to the website team for considering this, and for the excellent website!

@oldbutndy Yeah, this topic has been raised a few times on the forum. To me, it does seem like at this point the website's Devices page may be out of date on this issue.

I've made a post in the Design section of the forum, where I've seen the Website team post before.
