[VOLTE] Volte not working in Nextbit Robin [7.0]

I'm on Android 7.0 official, no root, no bootloader unlocked. I've Reliance Jio (which btw is LTE only) network. I can use internet fine on LTE but, calls doesn't work. I've enabled LTE enhanced mode. I also checked the apns. To place calls I've to use their 3rd party app which is pretty annoying. Any help?

Your carrier must not've cleared VOLTE for the Robin.

Just for a little bit of help, see if on your carriers website if they have a list of VOLTE compatable devices for their Network.

I go back and forth from India and US so I really need this to work with Jio LTE and VOLTE in India. Its listed on various sites as being compatible. Did you ever figure out why your phone wasn't getting VOLTE?

Not sure why it isn't working for you. When Jio was launched late last year, I use it for a month Nov-dec 2016 and it worked fine. Tried it again in Feb 2017 for a week and it was fine.
Are you using the stock launcher and dialer? The dialer had worked for me without any issue without installing any 3rd party dialer.

jio is woeking fine in robin i have tested it in delhi, nainital etc..
Jio is working on most of the custom roms and flawless on stock rom..

How to enable VoLTE on Pixel?

Hi guys.
Let me elaborate my question.
1. I am totally aware that VoLTE on Android at the moment generally requires the handset to be from the carrier, or from the same region as the carrier for it to have the correct VoLTE (and VoWIFI) settings.
2. I am also totally aware that since Android 6.0, there actually has been a provision to allow carriers to send carrier settings to the user. I also know that this isnt being widely used.
After my ownership of my Pixel XL, I moved to a HTC U11, which I have flashed a custom ROM. This custom ROM managed to have the carrier settings for VoLTE for my carrier baked in.
I am keen on getting a Pixel XL2, so Im keen to see what the Pixel community is doing to enable VoLTE on networks that arent stocking the Pixel or Pixel XL.
Here in Australia, both generations of the pixel seem like they will be Telstra exclusives. and I am not inclined to go on their network!
Thanks for any assistance!

I use it with T-Mobile, only Verizon stocks it in the States. Volte works fine for me. Nothing i needed to do other than to setup the phone with the Sim card in the device.

Same here, got it with my T-Mobile SIM card.

This worked for me. Go to dialer and dial
*#*#4636#*#*
Phone Information
Turn on VoLTE
Turn on Video Calling
Turn on Wi-Fi Calling
Exit

I'm on Oreo 8.1 on my P2 XL, looks like it's already enabled. I'm on AT&T.

Change carrier. AFAIK you'll never get enhanced LTE services using a non-AT&T branded phone on their network. Once I switched my pixel xl to T-Mobile things like that and wifi calling worked fine.

My condolences to your Pixel XL 2. I was in a Verizon store the other day just to check out PXL2. The blue tint when turning the phone horizontally - horrific. Also, barely faster than my Pixel XL, even if you care for that kind of thing (speed.)

Same problem in Argentina, Pixel is NOT SOLD here so.... out of luck, but I tried this (already knew of the menu) and all my options are blacked out -can't enable any of them-, advice?????
Thanks.

If you can get root on your phone, flash magisk and there is a module in there to install that can enable VoLte and Wifi calling, worked for me on AT&T.

I had to toggle VoLTE off then on, restart. It's working for me now

"Turn on Video Calling"
Option is disabled, couldn't turn on

Depends if you're on Verizon or straight talk or what. I'm on straight talk and they don't offer VOLTE even though they use Verizon towers.

Using *#*#4636#*#*, the VoLTE provisioned option is greyd out. Anyone has a solution for this?

It means your operator is not offering VoLTE, or, as in my case, Pixel XL is not approved by the operator. I have VoLTE on my SIM enabled and working with operator approved devices but network rejects Pixel as not compatible one.

Operator offers VoLTE and it doesn't filter IMEI like in some cases. Other not approved devices (e.g xiaomi, oneplus) managed to enable volte via shortcuts. I am asking for a similar workaround. --thanks

Of you're on Straight Talk you're SOL. They don't offer it even if you're using a Verizon SIM

If you had geryed provisioning options you need to use magisks voenabler. a did it right now on december pie update. Now I have all enabled. Just waiting for operator to enable volte for my number. I wonder it will active.

Hi, my carrier does support VoLTE but the Pixel is not on its whitelist.
When dialing *#*#4636#*#* and going into phone info, the switches for "VoLTE Provisioned" is off and greyed out, but at the top of this screen I see "Voice Network Type: LTE". Does that mean I am getting VoLTE? I cannot see any other sign or symbol when calling. (I know some devices have a VoLTE symbol either in the status bar or during a call)

Fake phone device model to network carrier

Hi,
I own an Oneplus 7T, which is VoLTE and VoWiFi enabled. Is it possible to make my network carrier believe I'm connecting with another phone model? Like a Xiaomi Redmi 10 for instance. I need my network carrier to stop disabling VoLTE and VoWifi from my subscription. It does so because I own a OP7T.
Here's the whole story...
The OP7T has two SIM slots and they are populated as so:
SIM 1: Orange Telecom (french)
SIM 2: Bouygues Telecom (french)
Orange won't recognize my phone as VoLTE or VoWifi compatible, whereas Bouygues does. I finally got in touch with a skilled employee there who told me that this is Orange's stupid politic to enable VoLTE only on phones they sell at their store! Gosh... There are some Xiaomi, Huawei, and fo course Samsung, Sony... but no Oneplus.
When I put my Orange SIM in a Samsung compatible phone, VoLTE and VoWifi work and remain ON, forever (I tried 3 weeks). If I switch to my OP7T, the VoLTE will work for 2 to 24 hours (very random) and then it turns OFF (only for the Orange SIM).
Ok, but why do I need this VoLTE and VoWifi so bad? Because I bought a Samsung Watch LTE, whose LTE option won't work if my carrier disables the VoLTE option!
=> I configure the Watch on my crappy Samsung phone, in which I've inserted the Orange SIM, and everythings works fine.
=> I put the Orange SIM in my OP7T and the Watch's LTE keeps working some hours (also the VoLTE sign is ON for SIM 1 & 2)
=> When the VoLTE sign disappears on my OP7T, for SIM 1, the Watch's LTE stops working too.
That turns me crazy... and Orange is the only carrier to provide a LTE option for my Watch so... I'm stuck. Of course, I don't want to buy another phone, this one is new
So, any way to fake my device for my carrier? Please...
Thank you!
Edit: my thread has been moved to the OP7T forum, but it does not belong here at all. That's a general Android phone question about chaing the model presented to the carrier. So I guess I'm not going to get any answer here...

volte and wifi calling only work for the sim you have as primary data. just making sure that's not your issue

Hi, thank you for the answer, however both work for both SIMs on my mobile. Also I can have LTE activated on obth SIMs at the same time, and for example keep the LTE data on on SIM2 while having a phone call on SIM1.
My issue is absolutely the one I described, which is that my carrier disable VOLTE when it recognize my mobile as being "incompatible" (so they say)

Something like this?

There's an xposed module which looks like it does what you want

Hello! I realize it's been quite some time since you posted this originally. Did you ever find a solution? I have a similar need for this

Following. I have the exact same problem. Don't have network at home and my carrier doesn't allow wifi calling for my device.

Same here . Trying to find a way around it ...

Question Realme Gt Master Edition VoWifi dont work?

it depend on your sim card carrier

I have been looking for that information, thinking about getting this phone to use T-Mobile USA GSM voLTE? is this phone compatible?

@ryantek No, it's not. I have been using Gt Master in Mint Mobile (which is T-Mobile MVNO) for 6 month and no VoLTE, no VoWifi. I could use mobile data, but even this was not very good, often gets stuck to 3g network, though GT Master supports most of the LTE bands used by T-Mobile (except for B71 600Mhz).
I had two long chats with Mint Mobile customer service, no resolution.
I believe it's gonna be even harder to activate it after July 1st, when T-Mobile will shutdown it's 3G network. Mint Mobile didn't make me any problems to buy and activate service, but now constantly bugs me to replace phone for compatible with their network.
I've also tried it with US Mobile (T-Mobile network), Boost Mobile (ATT) and couple others. The same effect.
Save yourself some trouble and buy phone that's on compatibility list: Oneplus, iPhone, Samsung or Motorola.
I bought Galaxy S22 and now use it as my main device in Google FI. GT Master still have active Mint Mobile simcard until 3rd of June, but after that it will be over.

Hi,
Thank you for sharing all of this information. It is sad to see the carriers in the USA do not support this phone. Sadly I will stay away until anyone can confirm a phone of this brand that works with VoLTE (Tmobile).
Once again Thank you.

Set up VoLTE and VoWiFi via QPST and the ( advaced pdc tool PDC ) Root is required. This option works in stock. You need to try several "choose" profiles, one will definitely go
In custom rom, if it doesn't work, just back up the EFS partition (after editing in stock rom) and restore it later in custom rom

I see. Wondering is there is a signed ROM with VolLTE enable out of the box.

Today I tried Google Fi simcard with my Realme GT Master (normal not modified ROM) and it worked!! VoLTE is working and so is VoWiFI (I think). I'm not 100% sure about VoWifi. I have icon of VoWifi during call but I can't make call just on WiFi while on Airplane Mode, I have to turn off Airplane Mode or it doesn't allow me to make a call.
Google Fi was activated with Galaxy S22 few months ago.
I'm not gonna test it for long, because I use Galaxy S22 as my main device now and in few days I'll move to US Mobile/Verizon, but Google Fi is usable. I still can't recommend buying GT Master for US: too much hassle, too many unknowns.

so basically you don't know which network you were on while VoLTE started to work? Google FI uses all three networks and switches them dynamically

As far as I know Google Fi uses two networks: Tmobile and Us Cellular. As I'm in western Massachusetts and US Cellular doesn't have coverage here, I'm pretty sure I got connected to T-Mobile. But I can't confirm it with 100% certainty.
