VoLTE & VoWiFi on O2? - Huawei Mate 10 Questions & Answers

Folks,
I know this has been discussed before, but those discussions are from last year, and things change, so...
Does VoLTE and VoWifi work OK on the Mate 10 Pro on O2? They work great on EE, but I'm thinking of changing to O2, and would like VoLTE and need VoWiFi (where I work is a cellular black hole due to thick steel/concrete walls).
I don't want to go to the bother of moving to O2 only to discover those don't work.
Thanks!

VoLTE and customization

I got a Z5 compact for my wife and she is on T Mobile and I would like to know if VoLTE on band 12 will work or do I need to flash a specific rom? The phone is an import with Greek customization. That is what I got from the eBay seller.
My z5c works on band 12 and has VoLTE in the quick settings but I suspect that is due to it running a Taiwan firmware. Doesn't matter because it doesn't work. Not sure how to get around that until Sony certifies with TMO, if ever. My z5p dual sim doesn't even have that option at all. One thing I have noticed is band 12 use is mostly non existent where I live. This thing seems to fight tooth & nail to stay on band 4 at the weakest signal rather than pick band 12. But my dual sim z5p on both TMO and ATT (I use both providers) the LTE doesn't seem to be that good at my house and I get much better reception on HSPA.

Mate 10 (standard or Pro version) VoLTE in the UK

Does anyone get VoLTE working on O2 or Three in the UK? Does the phone show any VoLTE icon on the notification bar or switch in settings?
Hi,
I've just got a Mate 10 (standard) ALP-L29 8..0.0.128 (C363) running on Three UK
Sadly neither Volte nor VoWifi work with Three
I'm hoping a rebrand to an European version might make it work, but am at a loss to know which version is possible and if it will even work.
Any advice appreciated
thanks
Which region do you buy the device from?
Bought from Wonda in Hong Kong who rebranded it to the above
It does not work on mine either. I am using ALP-AL00 8.0.0.126(SP2C00).
I am using ALP-AL00 8.0.0.126(SP2C00) and not working either.
I'm in the UK. on the three network running BLA-L09 8.0.0.124 (c782)... sometimes it pops up in the top left corner "Wi-Fi calling" ..... is this the same thing ??

If you mean wifi calling, I think it may be working on my O2 branded Mate 10 pro. Had to enable in the O2 app first.

No, VoLTE means not dropping to 3G when making calls. Does the signal drop to 3G when making calls without WiFi?
Does the signal drop to 3G when making calls without WiFi?
When making a call with three it automatically drops to 3g , I do get WiFi calling when my network signal is weak
On Three UK on Mate 10 pro. Not bought from Three. However on Vodafone VoLTE works... 3 claims ThreeinTouch app supports Supervoice/VoLTE though no options appear for me. Send a like and/or comment here on this tweet to Three UK. https://twitter.com/AminYacarEvaday/status/953734315560579073

Just got a Dual SIM Mate 10 Pro, and I have VoLTE working on Three UK.
I did a fair bit of research in to VoLTE / Wifi Calling (lots of lurking on these forms) before I got it, as access to SuperVoice would have been a dealbreaker if I couldn't get it (and other networks' full 4g spectrum).
It's worth understanding how Three currently structure their spectrum in the UK. I did a lot of head scratching when I used to have an iPhone, as despite Three texting me to say I was in a SuperVoice 4g area, my calls mostly dropped down to 3g.
Three have lots of high frequency 3g and 4g spectrum. They also have some low frequency 4g spectrum (band 20, 800Mhz), but there's a bit less of that.
Three's SuperVoice (VoLTE) only runs on the low frequency 4g 800mhz. The high frequency 4g does not carry VoLTE.
So - if you're on the high frequency 4g band (which is set by Three to be the first choice for locking on to) and you make a call, you need to get bumped to another band. If you're in range of 3g, and get so much as a whiff of it, it'll put you on that. If you can't get any 3g, but you can get lower frequency 4g (it travels further / deeper), it'll allow you on to that band and then - and only then - will you be able to make a VoLTE call.
Maybe one day Three will open up their higher frequency 4g to VoLTE if they restructure their spectrum, but I speculate that for the moment with the spectrum structured as it is, there isn't the justification for taking up high frequency 4g bandwidth with VoLTE call traffic, if there's increasingly unused 3g capacity sat alongside it. If however a phone is out of range of the high frequency 3g signal, the phone can use the low frequency 4g VoLTE for calling and, as Three put it, 'banish the indoor blackspots'.
My Mate 10 Pro is working in exactly the same way as my old iPhone used to - in that if there's any 3g whatsoever, it uses that for calls, often dropping to 3g from the higher frequency 4g (that doesn't allow VoLTE). It's only if you're somewhere where there's no 3g but there is 800mhz 4g, that you can use VoLTE. That makes testing it really hard! I've only had the Mate 10 for 2 days, and managed 2 VoLTE calls in a rural location. Near home I don't see VoLTE at all as there's very decent high frequency 3g coverage.
I also get the Wifi calling option in settings, however I haven't tested that yet, as I haven't been anywhere in the 2 days of phone ownership where mobile reception has been poor and there's been accessible Wifi to fall back on. There is no VoLTE toggle in settings, nor an icon in the status bar - the phone just quietly made a call over 4g (checked by using the 4g icon next to the signal bars, and using the settings>system>about phone>status>network menu whilst on a call to see whether the mobile network type remained 4g).
I'm hoping to test VoLTE on other networks shortly using my 2nd sim slot, however as the networks only allow VoLTE on contract it's not just a case of trying it out with a free PAYG SIM, unfortunately.
In terms of my phone, I ordered a Mate 10 Pro Dual sim Asian/International version (C636), that didn't seem to work with VoLTE (although as above it's hard to test with Three). If I'd have known that I could have bought a single SIM UK version and flashed new firmware to get dual sim I would have done to get a warranty, but when buying it I incorrectly thought maybe the hardware was different and I need 2 sims... I rebranded it to the Euro version (C432) and flashed Euro firmware, and I've since managed two VoLTE calls on Three UK. I'm hoping that other networks work as well... In hope of it doing so is partly why I bought the phone, and there are lots of reviews (that smell a bit of being paid for) that state Huawei has worked with networks to pre-install the VoLTE / Wifi Calling settings in to the Euro firmware.
Any questions just ask
The Pro was a Three exclusive so even if you buy a unbranded one it downloads Three firmware which allows Volte, the standard Mate 10 isn't a Three handset so wont have Volte
I don't think the unbranded phone will download Three firmware if it is on different generic firmware such as the AL00 model. However, VoLTE does have GSMA standard and iPhone has made VoLTE work around the world no matter where you buy the device.
That means Huawei is not actually showing the VoLTE toggle on Three. Based on the configuration files on the firmware of the ALP-AL00 model, I think not showing the VoLTE toggle is happening on O2 UK as well but I never get it working.
@evantkh
Yes, it seems that way, I made a few more calls over Three's 800mhz VoLTE yesterday so it's definitely working in line with Three's priority settings, there's just no toggle or icon. I also monitored using the LTE Monitor app to check the band and in all cases I was on 800mhz before making the call, maybe as it was the only band it could receive. I'm quite impressed with how seamlessly it works.
I don't have the same region as you, have you tried a rebrand and firmware flash to Euro? Mine didn't seem to work on the non Euro version, with the limited amount of testing I did before I flashed Euro firmware.
---------- Post added at 09:24 AM ---------- Previous post was at 09:19 AM ----------
Also, I can confirm WiFi calling works as well on Three. I saw that working yesterday, briefly.
I'm interested to know that you haven't seen VoLTE working on O2 - I was probably going to get my 2nd sim with them.
@Thasscas44
It's not worth re-branding and firmware flashing to Euro.
1. The hardware of AL00 model and L29 model are different at least the bands and possibly the security chip as well.
2. I will lose Huawei Pay functionality for NFC mobile payments in China.
3. I will only use O2 for a few months more as I am going to leave the UK in a few months.
Sounds fair enough, I changed region of my BLA L29 but not model. I definitely wouldn't have wanted to lose other functionality.
I've seen people say they've changed from an L09 to L29 but not the A00.
Err they don't stock the standard Mate 10 so the branded firmware doesn't exist

Question Nord 2 5G on Tombile in the USA

I based in the US and I am looking for a new phone, the lack of choice here is bad. Have you used this phone on Tmobile in the USA? Does this support Wifi Calling and Volte?

I have the EU/NA variant (DN2103) and I'm using it on T-Mobile in the USA. There are no options for Wifi calling or Volte and I'm unable to use any dialer codes to activate them. However, I do have good LTE service and everything works as expected. There are a lot of people in other countries on the OnePlus forums complaining at VoLTE not being supported and supposedly it has to be enabled for various carries by OnePlus. I'm hoping the Android 12 update will enable Wifi Calling and VoLTE, as it IS reportedly working on certain carriers in other countries.
That's disappointing, I had a Chinese version of the OnePlus 7 (Red!) for a brief period. I was surprised wifi call was working with it.

I'm suprised also. My OnePlus 6, 7 Pro and 7T all supported WIFI calling on T-Mobile, BUT they were all sold in the USA. The Nord 2 is not meant for USA consumption, so I have a feeling that's why it doesn't support wifi calling and VoLTE here.
Its still strange that i hadnthe chinese editon of the op7 had wifi calling working and the nord 2 doesnt, neither phone was for the US, maybe tmobile changed something

Question Help with 5G and VoLTE.

Hi guys!
I just got my Xperia 1 III but it doesn't have the 5G neither VoLTE option.
If someone here could point me in the right direction it'll be awesome!
Please help me, I'm with Telcel in Mexico, I have the 256GB version.
Are you subscribed for 5G with your provider ? VoLTE and VoWIFI also require subs. I have 5G and VoWifi. VoLTE isn't supported yet by my provider on this device.

Yup. And my own from the same network. Then I switched back to Vodafone.
Just an update, after reading one of the other posts on here, and checked then*#*#4636#*#* . I discovered I have the option of VoLTE, it's just not available on my phone tariff. I have VoWifi working fine.
It appears there's hope for us all yet .
Ps. Vowifi is showing not available, probably because I'm not not WiFi. And have good reception here . At home it definitely works.

most of the things should work
I did look on this specs first, after I got it seems like there is something additional. There is one spot I get a super connection but 90% of the time weak or no Service at all. I have tried many phones before but none of them even had such bad reception. And there supposed to be even the Tmobile 5G 71 Band. It looks to me someone sold a restricted fu.... Asia version without mentioning it
go to settings and all the way down you should see your model number. Considering that USA specific is not out yet you most likely have asian one which is XQ-CT72. EU one is CT54.
But those should work on t-mobile network, most of the bands are there. And those are low bands, so longer range.

It runs at limited feature support. Sony disables VoWIfi for US models and many other features including Bluetooth features such as Bluetooth meta data.
Sony blames T-Mobile for limited feature set. you will need to root your phone to hack up the build to enable VoWifi and other features.
This feud between Sony and T-Mobile has been going on for the past 10 years and Sony still playing ignorant to US market.
if you don't care about such limited feature set, Xperia 1 IV should still work on TMO
I just got my phone yesterday and realized the same thing happened to me, I didn't have service where I used to but I managed to get it working by: going to settings, then network and internet, then Sims, scroll down to access point names. And two options should pop up, I changed mine to T-mobile US LTE.. And restart, which worked for me.

that is correct, the issue is more related to Sony software rather than just the region. the only way to get VoWifi is to root your phone and disable sony software limitations

Getting VoLTE and VoWiFi on unlisted carriers by flashing mbn file
I live in Canada and I have a BC72 (Asian version). I am struggling to get VoLTE and VoWiFi working. I know that mbn file is the key to getting IMS support and sony seems to block some carrier mbn files (only mbn in sales areas are available). So...
forum.xda-developers.com
I have been using the XQ-CT72 here in michigan on GoogleFi, which is basically t-mobile, in my town where I live, I get 5G without doing anything to the phone, but with that said, I work 20 miles out in rural area and apparently from my research tmobile use band 71 for 5G in rural areas, I can get LTE+ but no 5g at work, my Pixel 6 pro can get 5g but its like 1 to 2 bars that`s it, but with my sony I get full bars of better signal on LTE+ with my Sony, since the Sony is missing the n71 band for 5G, but I`m fine with what I get, since at work I` m on wifi anyways, I`m happy with my purchase, I originally had the US model on pre-order and the release date was pushed back to Sept. 22-23, so I cancelled my pre-order and bought a new one on ebay for 1069.00 compared to sony wanted 1599.00 for US mode
EDIT: I ended up send it back to seller, the 5g icon was not really 5g, if you're in the USA I would wait and buy the USA version, which I pre-ordered from Sony website, expected ship date is 22-23
moving to GoogleFI is the best option to use this phone in the USA. it will utilize Tmobile USA and have all feature enables.

Only way to know for sure it to just buy it and try it for your usecases. Just buy it somewhere with a good return policy. I bought mine on Ebay with a 30-day return policy and so far it works fine on AT&T. Just make sure you do the trick where you disable dual-sim. (Google the details, it's somewhere here on XDA or on Reddit).
I bought my USA variant phone a week ago, and everything on T-Mobile works with the exception of Wi-Fi calling. The only alternative we have is to stop using T-Mobile and switch over to Google fi which does support Wi-Fi calling. Other than that my phone is flying super smooth and with fast performance like I've never believed compared to my old LG v30 Plus. I'm definitely impressed with this phone.

From a technical point of view, the phone should work on all carriers in the USA without issues, (with the exception of the Sony/T-Mobile Wi-Fi Calling issue that forces those who want Wi-Fi calling to switch to Google Fi, Mint Mobile, and other MVNOs).
Whatever service is in the area should work. Verizon will provision your phone to work with it's network. CDMA based carriers are supported per Sony's phone settings, so I would just go for it.
