Hello there!
So I've been watching this forum for a solution a long time ago now and I've seen that there's a plenty of you, who didn't find any solution just like me. Because I didn't want to ruin my phone with unlocking and root. But I managed to make it work, not just volte, but vowifi too. All you need is another phone that works on VoLTE (and/or vowifi) in the same country ( same carrier is better bu not requirement). Put your SIM card in that phone, enable VoLTE (and VoWifi) and put it back in your Xperia. For me, it worked with a T-mobile HU SIM card (They don't even have on sell this phone ). It was in my iPhone 8 plus, it had working VoLTE and VoWifi. When I put it in my Xperia both options popped up in the settings and they both worked like a charm. My perso SIM is a Yettel HU one (I bought the Xperia from them), it isn't VoLTE enabled by carrier, so I'll contact them today about it.
Hope, you guys manage to make them work too

Tried that yesterday, didn't work still. If I am right, I believe that the issue is that there is no network provider in my country that supports (has customised firmware) this phone.
I do a bit of travelling every once in a while; so my best bet is taking my phone in by a network provider in a country where this phone is sold and get that network provider to flash their firmware in it, buy a local sim card and have them make VoLTE work in it. Then my home SIM card should work with VoLTE afterwards.

Sorry to hear that it didn't work for you. In my country we have only one carrier (Yettel HU) that sells this phone. They use the international one XQ-BC52 Customised EEA. I bought it from them, so mine is also that. Idk but it did work for me. So they don't have own firmware. They had on Xperia z3, since then they sell unlocked devices.
My model is originally the xq62 but i flashed hybrid of xq72 SEA to make it work but it didnt so i just kept using it as it is. I tried this on this and still it dosent work. Maybe if i flash same model as yours xq52 or the original 62. Too much flashing and checking.....

I have no idea why does it work for some and why it doesn't for others. My perso SIM was voLTE disabled in their system. Maybe it's your case too. Call your provider's tech support (or so) and ask them about it, worth a try

Telecom Italy appear to never turn on VoLTE if not specifically asked, even if your telecom app say VoLTE enabled. I also had to ask multiple times till i was able o talk with an higher tier "technician".
This remember me when at work (AASP) we need to talk with ACS to solve an issue with various customers Apple products. Sometimes only escalating to higher tier will allow us to solve something. Lower tier employee, even for ISP, sometimes are not able/allowed to disclose something

But if it would be disabled in their system why would it work in other device? Should not work on any device right?

Mine didn't work in my iPhone either. It turned out that it can be disabled in 2-ways at my carrier. There's an android and ios disable option after it has been enabled, still no volte, but after I put it in iPhone (volte works) and put it back then it worked in Xperia too maybe that's a coincidence but I searched the internet a bit and I found some guys who made it work like this too.

What is the app bro?
Related
Hello from Japan.
I bought the s9+ online. It does support my carriers signal LTE. I`m with KDDI AU
what happens though is i cannot get signal. Though the sim is read and it knows the number attached. I cannot attach to the network.
There are 2 choices in manual search. i choose 1 it says I am not allowed on. the other just says registering for a long while then it fails.
I have found japanese forums blogs etc That AU are a bunch of turd munching ass bandits. I think they purposely try to stop anyone from BYOD by making it difficult.
In the case of VOLTE I have a s7 edge right now. It is on a VOLTE plan and has a sim that AU calls "AU ic lte card 06"
It seems that this sim only works in an VOLTE enabled device. (perhaps running firmware that add software to authenticate to network too) I.e. that sim will not attach in a non volte handset and some non au sold phones may not work either VOLTE support or not.
There is another sim coded 04 i think that works on lte/cdma hybrid. Since the galaxy s9+ does not work the cdma even if i changed the sim ( they charge about $30 and changed the plan from a volte plan to an lte plan another $30 charge) i could only use data anyway.
So I had thought this device would work since it was meant to be volte. but my device does not let me enable it. (some error like not supported by your current software version)
Anyone got any idea how to enable the volte is.
I don`t want to root it or load another rom etc.
So if there is not other way I may just cut my losses and switch providers.
I want to because I hate AU but at he same time i dont want to because they make it incredibly hard to change providers.
I've got the Snapdragon dual-sim Hong Kong model (SM-G9650 DS). I think this would apply to basically every model, though.
I'd like to find a way to enable VoLTE for carriers which support it, but for which the CSC on the phone doesn't support it, and for which there is no available CSC which supports it. In my case, I'd like VoLTE to work on Verizon in the US, and for Japanese carriers AU and Softbank. I'm sure there are lots of people who would like to get VoLTE in India working on Snapdragon models as well.
I enjoy having Samsung Pay, so I'd like to be able to do this without tripping Knox/rooting.
I've done as much studying on the subject as I could, and apparently, such a thing used to be possible by accessing IMS Settings through a shortcut app, but as of Samsung's Oreo update, it's not possible to do this without root anymore, it would seem.
Generally, on my phone, I try to enable VoLTE (there's an option in the quick toggles, but not an option in mobile network settings) and I get the message, "VoLTE is not supported by your current software version. Contact customer service for more details." This is on the Hong Kong version.
Oddly, after playing with several different CSCs and software versions, then finally coming back to the Hong Kong one and doing several factory resets, I had the option to enable VoLTE in mobile network settings, and it actually let me turn it on. I was surprised! Then, after taking out the sim, using another sim (to see if I could get VoLTE on it too, I couldn't), and putting the original one back in, it went back to not being possible. I may have triggered some kind of bug to allow me to do this, as this was with a Japanese Softbank SIM, for which VoLTE generally isn't supported on non-Japanese Samsung models. However, since then, I haven't been able to get the setting back.
I bought a Hong Kong sim just to test this, and every time I put in the Hong Kong sim, even though it's not activated, it immediately offers the ability to enable VoLTE, so it's probably restricted by MCC/MNC, allowing VoLTE to be enabled only on SIMs which are pre-approved by the CSC.
Anyway, I'd really like to ask the community if there may be anything I can try to get it working. I'm sure that if I root and trip Knox I could do it, but if there's some way to do it without having to trip Knox, and without having to factory reset every time I want to change SIMs, it would be great.
Let's figure this out!
That would be awesome!!
Following.
I have this phone too and currently have TMobile and would love to use volte and wifi calling.
Even i am searching the work around for this issue.
I am having TMobile note 8 and using it in india it does not allow me to enable volte on oreo.
I have to be on noughat to use volte service else its of no use.
Can anybody talk with shortcut master app dev if he got any solution to it?
I get VoLTE but don't have the option in the mobile network settings... For some reason it always takes a few hours for it to activate after I restart the phone.
Also I feel like maybe it didn't activate the first time until I enabled VoWiFi once.

How? Which Carrier?
Hey man,
I am in the same boat. I got S9 SM-G960U1 from USA and I'm in India. VOLTE does not work and am searching for a work around.
I am thinking of flashing a firmware with a different CSC file. But am skeptical.
i"m in the same situation !
Has anyone enable this yet?
I have galxy s9+ g9650 i wanted to use volte has anyone figured this yet. Will csc version change help in any way,also what csc version is best suitable in india and also how can i use samsung pay and other samsung apps??
Please help.
Thanks in advance
Hi there,
I've recently got the SM-G9910 HK version (TGY) and was wondering if there's any way to get eSim support? I'll be using this phone mainly in AT, however eSIM would be really nice.
Reading through various threads here I've learned that it might not be likely, unless changing the CSC which might imply certain "challenges" after it.
Any feedback / direction would be highly appreciated.
Anyway if this is the only "drawback" I might live with as the 888 SoC is more important to me than the current eSim support.
Thanks!
Just read a article on this, these phone already have it but not supported buy carriers yet. T-mobile might be the first to implement it though

Hi,
Yes, I've read the same, so far the Note 20 has been getting now the esim support with the latest update on t-mobile US => so there might be hope (definitely not a hardware issue).
However, according to Samsung HK live chat it's a hardware issue and thus not supported.
Let's see what future will bring this year.
It's somehow a disappointment to have this better SOC and no esim still
my s21 ultra is thru verizon. although we cant see the second imei number. they can see it. just call them ask for the second imei number registered with your phone. and then you can setup esim with another carrier. thats what i did. i have verizon as my main carrier and tmobile as the second on the esim.
@[email protected]: sounds like a great hack - would be interesting to see if others can confirm this outside of US?
I have Dual SIM on the 9910 - can imagine the second IMEI (which I can see) is just physical ? for an eSIM it would mean that either the device can bridge the IMEI for eSim or a 3rd IMEI would be required (which i doubt).
If you want I can Show you how to create a shortcut to enable mutilply sim. Sim1 and sim2. On the us s21 ultra version
actually, as I do have a HK version, with dual-SIM already enabled I would be rather interested in eSIM if there would be any way.
does your approach require root access?
Hi guys,
I also have a G9910 and I'd love to enable eSIM.
Have you had any luck so far?
Thanks,
Alex
Hi Alex - no luck so far - let's see if they'll ever do anything about this.

I just received my Xperia 1 IV USA version today from FocusCamera.com today, I was a little skeptical if it was even the USA version, since it wasn`t shipping from Sony until next week, I originally had pre-ordered on Sony website, then with a little looking around I had found the USA version on ebay in-stock, then I saw the seller name and went to there website yesterday and verified with there live chat that in fact it was in stock and would ship, so I ordered and use next day air shipping, everything works flawless and actually has the 5G bands like my Pixel 6 Pro, so I can get proper 5g speeds, on Band N71, That was missing from the Global version I was using 2 weeks ago, now I need the Firmware from Sony so I can root. I`m a happy camper
Congratulations
What carrier are you using it on?

yeah I had t-mobile then I switched to GoogleFi last month, and wifi calling works perfect, inside my work place service from all carriers suck, since it big steel building, but my Xperia 1 IV will say emergency calls only, but I can receive calls and make calls and receive text, ad everything just like had full bars of carrier service.
I guess you were not able to root it?
To know exactly how capable the device is then its necessary take modem logs and let smart people parse it.

Unfortunately not, so this will be going back for refund, I can`t justify spending 1600.00 on phone and not able to root and do with it what I want with it, but there`s always the global version I could go back too, I`m going return it and wait and see if Sony does eventually allow it to unlock the bootloader, until then I`ll just use my Pixel 6 pro for now.
Can you please let me know if :
a. the NA model has Dual SIM support ?
b. Face unlock works (was told the fingerprint scanner is a bit finicky)

a. there is dual sim support, but you will lose the micosd card, because Sim 2 uses the microsd slot
b. no face unlock and both global and USA version`s the fingerprint readers worked perfect.
Is the 5G SA standalone or NSA only?
Should be both on all versions, USA model difference is mmWave support.
Would also like to know if they finally enabled 5G SA on T-Mobile with this year models.

You can know that without buying phone. Download the firmware with xperifirm, extract modem.img and use ELFextract to extract your hw variants .mbn file. This will reveal the carrier/band policy files (in policyman folder) which live in the modem. There you can see which bands are enabled for specific operators and if they are enabled for SA and NSA.

Thanks for the tip. I got as far as extracting mbn files. I can't seem to find ELFextract tool you've mentioned. I'm assuming this is different than readelf utility.

Hi, i bought a unlocked xq-bc62 in US. I travel a lot and discovered 5G won't work in several carriers networks, no matter what I do in the phone ( I spend more time outside US). I called the carriers support and they confirmed their network doesn't have any lock preventing the use of overseas 5G bought phones. So far, I tried to use it in Portugal, UK, Ireland and Brazil but 5G is not recognized by the phone. I changed the sim for a 5G local one, changed ASN, manually chose network (5G ones are not displayed) and no success. I even tried to pray, but again, no success. I contacted Sony Support and they said phone will only work in 5G in 2 of the 3 main carriers in US and not outside US, despite the phone tech specs says it will work in all the frequencys used by above carriers. There are some threads here that confirm xq-bc62 Is not a full 5g phone. All said and done, my Question: is it possible to flash another region Image like xq-bc52 or xq-bc72 in this hardware? Will it work fine and, mainly, will 5G networks be accessible outside US? Tks
Some times its hardware but you can try mtk engineer mode settings there may be something of use there
If you can get the original vendor file usually have (user low ship...) its usually international
Unless the phone is using 4.5G and not real 5G

Yep, the US models have numerous disabled features and run late on updates. I've also noticed it's crippled or disabled while roaming. I'm not sure if it's directly from disabled features or it it has been blocked by telcos because it malfunctions. (It gets kicked off cell towers in the US)
The US model has slightly different radio hardware so I would expect problems flashing the OS from another region. There are some tricks for changing the feature lists that might be a safer bet.

How would one check what is and isn't turned on network wise??
I was able to flash the XQ-BC52 ROM in my XQ-BC62 hardware. So far, working fine in 4G+, but I´m in area with no 5G coverage. Tomorrow I will go to an 5G area and check f it worked. If not, I will try the XQ-BC72. I will keep you posted.

Maybe something along the lines of Getting VoLTE and VoWiFi on unlisted carriers by flashing mbn file or 5II/1&5III VoLTE patch. [Guide to release the root] or https://band.radio/
I haven't rooted yet so I haven't tried them. I bring a T-Mobile LG Velvet 5G with me when I travel. It's a little slower but doesn't have all the telco problems.
Test done, xqbc-52 doesn't see 5G network as well. XQ-BC72 SEA is a no go, don't even recognize the SIM card in the phone.
Will try another firmwares and the tweaks kevinmcmurtrie mentioned above, but my feeling is: I paid the 5G price for the Phone and actually got a a 4G Phone. Very frustrated with Sony. Thinking seriously about going back to Samsung.

But hey here's the pros, best physical camera sensors, Micro SD card Slot and headphone jack...
UPDATE!!! 5G is working!!!!! After Several Attempts, I finally got 5G. What worked for me, in Claro BR Network, was flash a Hybrid ROM. I Flashed A XQ-BC52 ROM with Modem files from XQ-BC72. So far everything working as it should. My only concern, next month I will be in Germany, may I have trouble in LTE over there with XQ-BC72 modems?

Tks for the spirits up Ainz_Ooal_Gown. The main reason I Bougth Sony 1 iii is the 3,5 mm jack. I hate USB adapters......
Ok, major setback. it worked for 3 hours and when I turned on my second Sim card the phone 5G was gone. Turned it off, reset radio configs, but no success. Apparently turning the second sim on override the BC72 configs. Time to get serious now and root the phone, what I'm very reluctant to do.

I am on Mint, T-mobile towers. 5G works great, has to be in your settings. For MMS use the T-mobile APN settings.
I would like to activate 4g+ on my xq-bc52!
how to do ?
thank you.
