VoLTE Telstra Australia

Just wondering whether anyone has managed to get VoLTE working with the Axon 7 on Telstra in Australia. Stock or LOS Rom? Cheers

SD820 SoC supports it but seeing that Australia is still so minutes and data sepparated with calls, maybe not really wise to use it here yet. There's no selections to enable/disable VoLTE in settings in stock ROM. Might be able to access hidden system settings in an engineering mode through the dialler though.
I have my personal Aldi SIM (runs off Telstra network) and work Telstra SIM in my Axon 7 but decided to leave VoLTE as a curiosity for now. Both SIMs show as 4G+ in statusbar. I suspect that means carrier aggregation.

4G+ is just faster than 4G, but many people report that they need to be very close to a cell tower to receive it.
That's literally everything I know lol

There is an option in settings to enable or disable it on stock ROM ,or is this different?
And Axon7 doesn't have 2CA or more so it can't aggregate 2 bands together, although it shows 4g+.

Yea I really want the VoWifi feature, due to being in a bit of a blackspot for reception, which can't happen until VoLTE is working. I don't have the option in settings, and I've tried enabling it through the engineering menu but it doesn't stick. I believe they (Telstra) may have it limited to certain devices with specific compatible firmware at this stage.

Thats exactly the menu option I don't have. Are you using A2017G on Telstra?

No I'm using a different carrier and that option is in the settings and I've got A2017.
Also I could never use VoLTE , because my provider has enabled for certain devices.
But I see in Network Cell Info app that it says this device doesn't have VoLTE capability.

The option doesn't exist in my ROM. Australian ROM and assuming the option is missing for good reason.

Is that the Nougat B04 firmware? I think the first version for A2017G to have VoLTE at all is the new German B08 firmware.

Yes, B04, waiting to see if ZTE give us Oreo but not expecting it now. Looks like they may not do an Axon 8, releasing fads like the foldable phone instead. This may be the first and only ZTE I ever own.

I'm at Jenolan Caves right now for my wedding anniversary. All we get is 3G here so VoLTE would be useless. I'm not modding anything to enable it as I think it would actually compromise my phone's performance in Australia because I do turn off cellular data and rely on wifi frequently, like at work or home.
I'm not convinced the Axon 7 doesn't have VoLTE, I think it's just not enabled by the software.
I was sure I had seen something about 4G+ and here is copy paste from it.
"LTE-A/4G+ is actually an amalgamation of several different technologies. The biggest of these is called “carrier aggregation.” It’s kind of a misnomer, as it has nothing to do with aggregating wireless carriers. What it does, in a very simplified form, is allow your device to send and receive data from two different frequencies (known as bands) at the same time, which translates to faster speeds."
I also entered a sort of engineer mode through the dialler and screenshot it with it scrolled a bit to hide my IMEI. The phone shows VoLTE amongst other things and mentions not provisioned so seems to me software switch and carrier support but the phone would do it if the carrier allowed.

@ sirizak, I am sorry that there is no FM for A2017G in your country.

Can't make or receive calls

Hi,
Since I got the phone, I was unable to receive or make outgoing calls on my MI A1.
Data and txt msging works and I have tried separate sim cards that work in a different phone and was unable to call from the MI A1 so it isn't my sim card that is the problem.
I have tried putting my sim in both the first and the second slot to no avail.
When I have it set to 4g or 2g it begins a call and it hangs up automatically after a minute if I use 3g it is unable to make a call and instantly hangs up.
The phone is running 8.0.0 version of Android.
Thanks in advance for any advice.

Check your APN settings in the phone, my network provider did not send them automatically and I had to input them in manually, when I checked my APN it was blank!

I went into network settings and checked my APN settings, they weren't blank. However, I tried and made a new APN that my provider uses, still no luck when calling.
While in the network setting I tried choosing a network and registered my provider's network. This time I got the error notification "Selected network is unavailable" with the dailer giving me "Mobile network not available"
Is it possible that calling is not supported, but 4g and data are?

What country are you in and what band does your provider use?
Also what A1 do you have, it's printed on the back of phone: MDI2 (India) & MDG2 (Global)?
If it's global it will also have a big red sticker on both sides of the box saying "Global Version".
Even with a global phone, still check the bands your provider uses matches the bands your phone has.
MDI2 has limited bands, no band 20 for instance which would stop it connecting in many country's.

Sorry I just read you have data so it cant be the bands Mmmmmmm.

Did you ever figure it out? I'm on t-mobile in the US also and calls only work sometimes. I notice that when making or receiving a call the 4G indicator in the status bar will disappear. Seems like the phone is switching to a different band just to make calls and sometimes it can't switch fast enough so the call is missed.

Nope, I returned it.

Mine worked perfectly for nearly a year, and started this about a month ago after an update. So I can no longer return it, but it's pretty useless without calling capability. Anybody else have any ideas?

I have the same problem.

No

No VoLTE & SIM 2 mostly switches to 2G

I have 2 SIMs (Both 4G/VoLTE) but none seem to work with Max Pro M2. Is there any issue with VoLTE?
One is from Airtel another from Idea.
I even tried *#*#4636#*#* and forcing LTE but the issue is after reboot the menu changes back to TD-SCDMA/CDMA/UTMS
Mobile Radio Power and VoLTE Provisioned show Green
Voice / Data network type show LTE
In settings Enhanced VoLTE is enabled and Select Network 4G Preferred.
Also as its a Dual SIM phone after dialing *#*#4636#*#* only one SIM shows up in the menu for settings so I have to disable one sim and update setting.
But settings dont stay and keep changing back.
Mobile Operators say that VoLTE is enabled for my number and should work but not working. Any help? Or anyone else facing this issue?
Thanks

For me also airtel volte did not work. Switched to jio where it worked. Cant say about idea.

I am having the same issue. I tried this and still doesn't show.
Anything else I can try.
My issues is that the phone connects to the carrier network . I can send/receive text messages and I can use data, but I cannot make or receive calls.
I contacted the carrier and they suggested I enable VoLTE but I do not have that option in any settings.

Data gone when call comes.

I'm on latest ROS MIUI and while playing game of streaming YouTube if I get a call my Data is disabled. Please help. Thanks

Your explanation is not clear. It looks like some words are arranged randomly, to form a sentence. Try being more clearer. Otherwise no one will be able to help you.

Okay I'll explain you the situation.
I play clash of clans and it works on internet connection. Yesterday I was playing it and my mom called on my phone. I didn't pick I just pushed up the call notification. I started getting weak signal message in game and my connection was lost.
After that I received a call again then I put call on speaker and turn on Data to use WhatsApp. When I send message it doesn't go. I think my internet connection stops when call is going on. Is it clear now? Sorry my Ingles is bad.

Yes it's lot more clear now. And about your issue, could it be a solution to use the "data during calls" toggle under your sim settings? Honestly, I don't know much about it, as I never have faced the scenario you just described. Anyway, if this doesn't help, I hope someone with a better idea will answer you. Good luck!

There's no such option in Sim I checked before. Maybe something to do with firmware. Anyway thanks for help.

It is normal, you are playing games in 4g/LTE mode but when you got a call your sim mode needs to switch to 3g mode. That's the reason you got a slower internet connection while there is calling. The VoLTE mode is what you need, for you to use data connection while you are talking to someone in a call, but i think you sim card doesn't support VoLTE mode. Try to research about your sim card if it's VoLTE capable. Here in the philippines there is no VoLTE capable sim. I hope this helps. Thanks.

Yes bro my sim is volte supported. Before I flashed cr 6.0 this never happened. But in cr 6.0 I started getting this problem. Even after switching to ROS MIUI it's there.

Do you have the volte icon on status bar? Maybe you network preference (GSM/WCDMA/LTE) is wrong, trying to use 2G/3G if available, instead 4G. Try to switch to "LTE only" and check if you can make call.

Not enough, you need to have volte (4G voice) activated on your sim card too!
I tried lte mode but can't use data while in call.
If in call the connection mode change from LTE/4G to H/3G or 2G, you don't have volte. Try to call somebody, and check the status bar network icon. Only 4G with volte able to have call and data same time.
I recently get volte working on my phone (after sending a "I want volte" mail to service provider).
This depend on service provider, some activating volte only for "officially supported" phones (my case), some automatically for all, and some have 4G network only for data and for voice using only the "old" 3G/2G.

Oh bro my sim card is already volte supported but still I wasn't getting volte. I fixed it by flashing 10.3.6 firmware in ofox. Now my volte is back.
