Can carrier decide which phone is VoLTE compatible? - General Questions and Answers

VoLTE was launched for the first time in India by Jio.com. Subsequently it was launched by Airtel, Vodafone, Idea in select circles. Any phone which works as VoLTE on Jio should work on other operators as well, isn't it?
I have following VoLTE phones:
Samsung Galaxy on7 pro
Meizu C9
Both phones show VOLTE sign when I insert Jio sim in first slot.
Yesterday I upgraded my Vodafone 3G sim into 4G sim and tried in both these phones in first slot. Vodafone has launched VoLTE in my circle but I don't see VOLTE sign on the phone. I see only 4G sign.
My question is "Can carrier selectively allow certain Brand/Model phones as VoLTE?"

VoLTE is absolutely controlled by the carrier. Just because you have VoLTE on a device with "this" carrier, does not mean that the device will still be able to use VoLTE with "that" carrier. If the new carrier offers VoLTE for your device, you can use VoLTE but if the new carrier does not offer VoLTE for your device, you will not have VoLTE with that carrier. It is not a matter of whether the carrier supports VoLTE, it is a matter of whether they offer VoLTE support for your specific device.

If you think about it, it is probably because some networks don't have the logistics to support every device with VoLTE. It requires modifications to ther system for each different device to add them to their list of supported devices.
Also, MVNO networks or subcontracted networks have to pay the network that they are subcontracted with for the data that their customers use. The more customers use VoLTE, the more data is being used. The more data their customers use, the more it costs them to pay their parent network for the that is used.

If VoLTE is a feature of Android Operating System how come the carrier needs to support each device?

Vodafone have their own network. There is another company Idea which uses their network for 4G services (Off course both companies merged recently). Idea does not offer VoLTE in Delhi. Idea offers VoLTE in other circles where they have their own 4G network. Idea also offers on certain phones only.
I think this is more about using 4G, 3G/2G resources in an optimized manner.

That's exactly what I meant, optimizing 4G usage keeps their costs down. Pretty much, everything a company does is all about money and controlling the market/consumer.

VoLTE and VoWIFI

Did anybody found the settings for WIFI-Call or VoLTE ?
Nothing found for Vodafone/Germany on my Z6.
No VoLTE certification on United States carriers has been the norm.

I currently own an OG Pixel from 2016 and it does not have those bands you quote in the HardForum (66, 71) and yet my Pixel operates great on my area. Are those bands important for use in your area? TMobile is my carrier if that helps any. I plan on purchasing it without a doubt.

I am on TMobile too currently running with a Moto G6. It has band 66 but not band 71 , and like your phone it runs great in my area too. However, I never have had a need to use band 66 or 71 . The only reason I mentioned the ZenFone 6 not having band 66 and 71 is some owners have the need (remote area, penetration of a building in the area where they are, etc).
What is critical for me is how will not having VoLTE affect my call quality?
Every phone I ever owned has had VoLTE as does your Pixel. For experimentation I toggled my phone's Preferred Network Type to 3G and made some calls to a robotic answering service and listened to their recordings and couldn't discern any difference in incoming voice quality when compared to 4G LTE. Incoming call quality over 2G however, sounded all muffled and terrible as would be expected.
Granted that is not an ideal way to test out call quality, better would be to make calls to different people over 4G and 3G and assess how they sound to me - and ask how I sound to them. But I have been reluctant to bug any of my handful of friends to do this with me.
My local TMobile outlet tells me that I shouldn't expect any loss of calling sound quality over their 3G network towers because TMobile is continually making tweaks to optimize them as part of their ongoing tower maintenance.
However, if you listen to what TMobile and others have to say about VoLTE it reads like this...
TMobile Support: VoLTE
VoLTE (Voice over LTE) allows you to place and receive calls on our LTE data network, and it's available nationwide.
Placing a call connects twice as fast.
Switching between 4G VoLTE and Wi-Fi Calling does not drop a call.
HD Voice on VoLTE
HD Voice is a feature that improves in-call voice quality nationwide for compatible phones.
Voice call quality is more true-to-life, with less background noise.
It automatically activates, if you and the person you're calling are both using supported phones on VoLTE.
What's your take on this VoLTE concern wreq5 ?
Would like to hear from you and others on this. In the past I've turned down flagship phones for not being able to make calls over TMobile VoLTE. And now a very attractive phone like the Zenfone 6 appears on the scene. Sure would like to have it, if only I could be assured that not having TMobile VoLTE provisioning would not be a concern.

This would not be a dealbreaker as my rural
need or getting great service in buildings is not that important but others, as yourself, do require it. As for phone calls, rarely happens for me, and I am a heavy texter so texting should be fine. The choice is yours.

I wrote above "I never have had a need to use band 66 or 71 ".
Pretty much any phone released today supports it but carriers require specific profiles for their network. There isn't a universal profile that I'm aware of. So when a carrier says your phone isn't supported or your phone does not support it, they mean that your phone isn't certified by them or have their specific network profile.
I'll admit I'm a bit uncertain on the process of getting a phone to work with the profiles in the sense that I don't know if Asus needs to do the leg work or it's the carrier. It's probably both. That's what's causing the more obscure phone models to be limited in regards to network-specific features. So if you want to ensure support, sadly you need to buy a more mainstream device.
I'm going to have to pass on this phone. Last week I contacted ASUS technical support and requested that the inclusion of bands 66 and 71 be made via a firmware update. I also asked if ASUS is planning to enable VoLTE on North American carriers. This was their response.

Hello xxxx ,
Thank you for your patience and patronage!
In regards of your escalated query, our engineering department confirms the enabling of any GSM LTE bands cannot be done within firmware since it's integrated in the hardware of the modem itself.
Also on all our current unlocked USA/CANADA Zenfones, we currently do not have support for Voice Over LTE VoLTE in our North American market at this time.

Pls can anybody check the functionality of VoLTE (wich country) and/or VoWiFi ?

From what I understand, you can call Tmobile and register your IMEI with them (unlocked device). After that VoLTE and Wifi calling will work, but not video calling.

are you sure i can call Tmobile and register your IMEI with them? and later will Volte and wifi calling work? Do you have confirmed information for this?
Which model note 10+ do I need to have? only with Snapdragon (of course I'm only interested in the dual sim version) will it also work on Exynos?

Essentially, you will only be able to connect to 1 LTE band at a time, which means you will see slower speeds compared to a US Note10+. Basically, no problem with LTE data but could have slower data speed sometimes compared to US Note10+.

Thank you now I understand. But this is not a problem for me because currently I have the same because I have a note 9 dual sim with exynos. More important for me, it's wifi calling and volte.
Can you add a few screen from settings folder with settings wifi calling and Volte?
do use now dual sim ? One sim it's from t-mobile and have wifi calling and second sim card does not work on wifi calling?

Settings screenies attached. I am using both sims as you can see I have 2 dialing buttons.
AT&T doesn't open up VoLTE and VoWifi to non whitelisted phones, so it only shows on one sim. I just turn the setting off because it doesn't work anyways.

Reviving an old post here...
Are you still using this device and still with AT&T and T-Mobile. Any long term issues or challenges?
I'm on the same carriers; T-Mobile personal (and primary) and AT&T (work). I'm most concerned about VoWiFi and VoLTE on T-Mobile. With AT&T, as long as it rings and I can get texts, I'm good.
Finally, I believe you said further up that you got it on ebay...any chance you recall the seller?
Thanks!

I am not in a rural area or a dense metro area so those do not affect my receptions. Also I mainly use AT&T and switch to T-Mobile for data depending on reception.
Speed wise, it will be slower on benchmarks due to the lack of carrier aggregation (and b29, b30 missing for AT&T), but it doesn't affect my real world usage: chat/email, web browsing, music streaming, remote desktop.

VOLTE On TMobile & ATT?

will volte work out the box for TMobile ? They won't activate phones on their network after a while if they don't support VOLTE.... Or any plans to update it in the near future. When will this go on sale in North America?
Sent from my ASUS_I01WDX using Tapatalk
I am currently on T-mo, it doesn't do VoLTE currently, I know its possible via root and changing parameters. ALSO they just enabled VoLTE for their ROG phone 3 via an update so I will assume they will probably do the same for the ZF7, if not I will have to root it.
I asked an asus rep about sale in NA and they didn't have an answer from marketing team, so I bought mine on eBay
I'm beginning to think they will sell in in america especially if they enable volte for TMobile like they did the rog 3. I'm waiting to see if they enable volte on the 6 and the 7.
And then there's the OnePlus 8T coming in going to weigh my optione

This guy apparently has VoLTE already on his phone, unsure how though.
Will this work on att in the states? Also which model if so?
ATT will ONLY work upto 3g. You will see an H on top the signal bar which indicates a Enhanced 3g speed also know as HSPA speed connection. I have tried 2 new sim cards. I have tried several APN's I have tried all updates and a reset. No 4G and no 5G on ATT. Unless someone can tell me something new, this phone will not FULLY work on ATT. Text works. Calls work. Internet is sort of hit and miss with decent signal but again rather slow.
T Mobile will ONLY work upto 4g. No Volte although it seems to have the capability of Volte it cant not work with Tmobile Volte because it seems the cell bands are not compatible. Text work. Internet works rather fast, Good solid signal however no 5G and no Volte due to incompatible cell bands.
I did research on this subject and found that the ATT cell bands for everything including 5G do seem to be compatible with the 7 pro but again, it does not FULLY work oddly
I also did research on Tmobile cell bands and the bands for 5G are not even close to being compatible. Volte is also non compatible. 4g is compatible and works..
THIS IS MY OWN PERSONAL EXPERIENCE TODAY AS I PURCHASED A SIM FROM EACH PROVIDER ( THIS IS A DUAL SIM PHONE) AND PLACED THEM BOTH IN THE PHONE.. I DID EXTENSIVE RESEARCH>>>
IF ANYONE CAN GET THE PHONE TO DO 4G or 5G ID APPRECIATE THAT INFO>>
ASUS NEEDS TO DO AN UPDAT FAST BEFORE PEOPLE START TO RETURN THIS DEVICE. THIS AGE IS ALL ABOUT 5 G.. THIS PHONE IS NOT COMPATIBLE WITH USA. I DO NOT SEE HOW AN UPDATE WILL FIX THE PROBLEM SINCE THE PHONE IS ONLY PHYSICALLY CABLE OF A SPECIFIC SET OF BANDS WHICH ARE NOT NOT NOT THE SAME AS USA BANDS

HD Audio/ VoLTE

Is there a setting to enable VoLTE or some sort of HD phone call audio? I searched everywhere and i can't find something... The top speaker sounds like the other person is on speaker and talking from the bathroom...
Yes it's in the "Network and Internet" settings, under the "Mobile network" category.
Sorry if the labels are different on your phone. I'm using it in French.

It probably depends on the SIM card.
You could try asking your mobile network provider for a new SIM card. But I'm not sure at all that would fix this.

My network operator is Orange/Sosh(France) and there is no option for the VoLTE.
Guys the truth is... The phone is compatible with only a limited set of band frequencies..
THIS MEANS
Volte, 4G 5G etc will ONLY WORK IF your cell phone provider has the same frequencies that the phone requires.
If you cant enable Volte, It wont work cause your phone is NOT capable of working on your Cell Providers cell tower freqncies. Each company uses a different Frequency
Here in USA
ATT will ONLY work upto 3g. You will see an H on top the signal bar which indicates a Enhanced 3g speed also know as HSPA speed connection. I have tried 2 new sim cards.

Question Usa carrier support

I've asked this question before and I can't find anything.
Can anybody confirm the 0/B/E versions to work on TMobile or att or mvnos of them?
If someone wants to be so kindid appreciate it. Really wanting to buy one for root.
if you use AT&T, don't buy any international models because they will block your sim. You may call them to unlock it but the sim will be blocked again after a couple days. The reason is AT&T has a list of supported models and international phones are not on their list.
T-Mobile doesn't have such a horrible thing. So yeah, it works.
Oh, and I am using 908E/DS on T-Mobile network.

That’s what I’ve done and been using till now. Bought the 908E on Amazon, unlocked the bootloader and rooted it. No custom rom for it yet other than tha Magisk rom by dr.ketan. I’ve always been an AT&T customer in so many years. They refused to work with me to make my phone work on their network so I switch to T-mobile.
I’m using the S22 Ultra 908E on T-mobile to write this right now. I don’t see any issue. If there is one, the phone is the issue.

The missing of band 71 if using on TMO, is a big loss. I wouldn't bother.

No. I don't expect an international phone to be fully working on a US carrier network such as TMO or ATT due to missing bands. If I have to choose between slower connection and the ability to root, I'd choose the latter one. I chose TMO because it works, white ATT not working at all.
There are wifi networks available almost everywhere I go nowadays. In case there is none, usually when I was driving, 4G/LTE always available and that's good enough.

So to confirm, no signal at all for att/cricket?
What about h20wireless? Redpocket mobile?
What site to use to check compatibility? I'll take slower speeds
To confirm:
1. AT&T blocks your sim right away. Your phone turns into a small tablet. That's it. Nothing you can do about it. I don't bother with smaller companies. I only go for the big boys.
2. T-Mobile will give you slower speed and freedom of root. This comes from my experience. Very little chance I need to use my plan's data. I can't tell the speed is slower at all. As far as carrier's features, I don't use any of them, but I think you can still have them if you change it to proper CSC.
Google search your model then you will find what bands your model support. Then Google search your choice of carrier to see what bands they have. Google is your friend.
Not just slower speed. Theres some areas that band 71 would be required to even get service at all in rural areas. Like just 5 min from my house if you have T-Mobile and your phone doesnt have band 71 no service.

This site is what I used and it looks like the version I want to get will suffice. But what do you think?

All depends on area. It's still missing band 71 and N71 5G. I personally couldn't as it would make my phone useless in areas I frequent

But you could get the 4G LTE tho at least right? I have a 5G phone and i only get LTE speeds which is fine but the carrier doesn't offer 5G.

No. Band 71 is an LTE band on TMobile.

In the end, as @hyelton just said, it all depends on your area, your luck and how you would use your phone... There is no definite answer to the op's question until he figures it out himself. It works for me and I am happy with what I got but that may not apply to everyone else... If the op decides to roll the dice for a chance to get a phone that he can have total freedom over it he can go for it. Otherwise, just buy the one on Samsung website ending with U models and have all of his worries put away. Honestly, I didn't think about any of that when I placed my order.
My unlocked 908U1 on t-mobile work perfectly, supported band25 with 130-180mbps speeds on LTE.
ps: 5G is totally disabled as it switching every 5 seconds between 4G\5G networks

My OP was based on the international versions because I absolutely have to have root. I have not owned a phone that I could not have root capabilities in over 10 years.
I don't care so much about 5G I just want to have a phone that functions on a US carrier from overseas. Maybe it got lost in translation but I just want to know what carriers people have and if anybody has the carriers that I mentioned with confirmation or denial of service.
Specifically the carriers on most questioned about are H2O wireless and red pocket. I'm not very Google friendly and so I'm not familiar with the bands I'm used to just buying a phone and it working as intended for my purposes.
^^^ You're overthinking it. Just pull up the bandwidths for the carrier you're looking to utilize and go from there. As mentioned you're better served by going for one of the major carriers and maybe their prepaid services. Remember major carriers prioritize their post paid plans first for their optimum network traffic followed by their own respective prepaid plans and finally the MVNOs. I would stay away from the MVNOs in your scenario if you're importing a handset not configured for the U.S to begin it and degrading it further by using an MVNO.
