@aimar Yes, GMT + 8, and notably, that linked site confirms that it indeed resets at midnight in China, not some other time of day. Useful!

There's an excellent post to help install on Redmi Note 9 Pro and similar devices. While of course there will be differences for yours, like firmware, I strongly suspect the basics of unlocking will be the same.
The other difference is that the post is from 2024, and it seems clear that Xiaomi has made it harder to unlock. But at least this shows you the process:

@aimar Yeah, I'd read something about that. It resets at a certain time of day, China time (one big time zone).. not sure if it's midnight or what. Worth looking into what time the daily quota resets.

@aimar Thanks for the tip, and for posting that link! I'll try it out. Meanwhile my existing phone, Oneplus N10 got VoLTE support, and my need for a different phone evaporated.
But I'd love to get UT working on that device.

Good luck getting yours unlocked! Seems it may be more a question of luck than anything else

@aimar It should just be a one week (168 hour, they'll say) wait.

I can't confirm what @kln_nurv said exactly, but it does kinda fit with my experience.

I bought a Xiaomi Redmi Note 9 Pro from the EU for delivery in Canada. I made a Xiaomi account, synced it to the phone, waited 168 days, but where it failed was as part of something Xiaomi called SIM sync or something similar. There was supposed to be a verification SMS from Xiaomi. This would never be received, and SIM Sync / SIM Activation would fail.

Then when I'd try Mi Unlock Tool even after 7 days, it would say the phone isn't "Activated".
A few emails with Xiaomi and a couple calls with my cellular carrier later, I gave up.

The best they could come up with at the time is that "short-code SMS", the type commonly used for 2FA, wasn't coming through maybe because either Xiaomi didn't have servers in Canada, or because it wasn't in its original market. They said short-code SMS don't work internationally. None of this made very much sense to me.

So I dunno, it's possible it now only works from within China.
I still have the phone. I will try to find time to make a new Xiaomi account via a Proton VPN server in Hong Kong and see if that works.. best I can do.

Any recent reports from others unlocking Xiaomi devices could be helpful. This was in 2026 that I was trying. Clearly people succeeded at this in the past. But anybody done so this year?

@gpatel-fr So far it seems that reliably I will get a ring when calling somebody from the same network as me. From Lucky Mobile, in Canada, it rings when I call someone using Lucky Mobile or Virgin Mobile, both of which are MVNOs on the Bell Network.
I don't think I'm hearing any rings when not doing that. Calling 1-800 numbers yielded mixed results, but consistently it would ring or not ring for a given number.

@gpatel-fr Yep, will definitely look out for network-related rings.

@gpatel-fr Your technical knowledge is greater than mine - I wouldn't know how to set up traces or look for sources of the issue without guidance. But if there are specific ways I can help test things out, let me know

@gandalf I can say that the first three items on your list do not occur for me on a Oneplus N10. I just tested to make sure. There are some times when it does seem to maybe get stuck reverting to 3G for calls (I now see an H in top indicator, for HSPA I guess) but WiFi doesn't trigger it for me.

@gpatel-fr I have also experienced the odd ring when dialing out since my OP N10 got VoLTE, but mostly not.
I thought maybe it was only occurring when I was connected over 3G, but no, after dialing some random 1-800 numbers it happens the same for a given number whether I'm on VoLTE or 3G/H.

I don't really see lack of ring as much of an issue (I'm still just amazed and grateful to have VoLTE!) but it's still worth trying to figure out when it does/doesn't happen. I'll start looking for whether its network dependent.

@tacofeast Yes, welcome!
It takes some considerable work to get Ubuntu Touch working on a given phone. There are no ports of Samsung phones at present, and porting is done by community members like yourself.
So to see UT running on those phones, you'd need to do the work, or find others interested in sharing that work. There's documentation on porting on the UBports website.

Alternately, there'd a list of already supported devices, and perhaps you could find one available used to test out the OS.

Has anybody had luck getting an unlock token from Oneplus for a BE2028 that was sold by a third party over amazon?
...
has anybody tried "adjusting" an invoice slightly?

@bunchy7s Note that the Oneplus 3 port isn't even listed on the main devices page. The page @moem dug up says that the last work on it was in 2021 and is for UT 16.04, which is quite out of date. And the video you followed is four years old.

I can't say that your issues are definitely caused by how out of date it is, but I can say that you're unlikely to have a good experience of Ubuntu Touch on that device.
Unless you want to take up the reins and bring the Oneplus 3 port up to date, I'd say your best bet to try UT is to read around on the forum and device pages and try to find a supported device that suits your needs and is affordable and available in your area.

Also of note: some people have difficulty with putting a phone back to android, so do your homework on that before attempting.. people have bricked their devices.

@chaosmaou VoLTE only landed on N10 in mid November, <4 months ago, so yes, it's worth trying again now that VoLTE is working.
Nobody is guaranteeing that it works perfectly / with all carriers, but so far results seem very good.

@rocket2nfinity I hadn't heard of a pending fix for group MMS. That's incredible news!

@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!
