No VoLTE support - Samsung Galaxy A51 Questions & Answers

I have installed Pixel Experience 13 Unofficial version in my A51. In the network types there are only 2 options like LTE and 3G.
The issue is, I live in India and I am using Jio sim card. Which probably doesn't work without VoLTE. I am not able to call/sms anyone nor I can receive anything. Internet works fine. But no calls/sms. Is there work around for this? Is there any other OS which probably supports VoLTE?

The phone has to support VoLTE , it is hardware/modem issue (if i am not mistaken)
so no software can fix that problem.
Phone had to support VoLTE type of a network when it was released.
Or find a provider that still supports just 3g/LTE without VoLTE
(i think they should still exist in india)

AOSP ROMs like Pixel Experience or LineageOS don't have VoLTE support on Samsung phones because of how Samsung implements it on their phones.
This has been the case for years and there doesn't seem to be any fix in sight.

How to add native VoLte support on G930T?

I am on latest firmware, no root. Why T-mobile disabled VoLte
I just downloaded the November security update, and VoLTE is enabled as it was before updating.
I've had it since I've been on the UnCarrier side of Tracfone (which is since I've had it active). Before I had it active, I was piloting a Galaxy Nexus (which supported neither VoLTE or VoWiFI); while it claimed to support LTE, it was trapped with LTE band 13, which does NOT support that LTE feature set very well, nor does it support VoLTE at all). I just re-enabled VoWiFi as a test (running the AT&T Oreo firmware - still on T-Mobile side of Tracfone).

VoLTE

VoLTE is new for me. Looked up already on google what's the meaning and I can't differentiate what is VoLTE or LTE only? I have seen this "VoLTE Provision" setting on Phone Information but I can't turn that on. Does that mean I don't have it? Btw I'm just using a stock rom non-rooted SM-G925K (Korean Variant). Could anyone expound that VoLTE to me? Whether it is really important or just an option.

Volte = Voice over LTE. It's similar to Wi-Fi call but uses LTE/4G data instead. It increases call quality. In order to use Volte you need to have a carrier that supports Volte as not all carriers do.

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.
See my comment in [H]ardForum Post #10 and the response in Post#12
Has anyone, anywhere ever had a carrier VoLTE certification for their ASUS phone?

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.
Best Regards,

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

Is adding bands via firmware possible? I'm unfamiliar of the tech but sounds like a hardware fix to me like they said.

Can carrier decide which phone is VoLTE compatible?

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 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
