Simultaneous Voice Call and Data

I have the international Exynos version of the S7 Edge and find cellular data stops working as soon as the phone gets on a voice call. The H+ symbol disappears, browsing stops working etc. At home it is not a problem as the phone is connected to Wifi and voice calls don't effect it, however, out and about, when on cellular data, internet is all lost.
Is it that the s7 doesn't allow simultaenous voice+Data?. I thought that was a problem with Verizon only, GSM (AT&T etc) versions don't have that problem?.

Have the same version and same issue. Heard that it's not possible to do voice and data together...Not sure how true it is

Got tmobile in the usa.
I have always been able to talk and use the net at the same time.
I do it all the time. Seems like no one knows how to looks stuff up so they always call me.
This worms for me on network 4g and wifi

I have the same problem on my g935f unlocked in europe, so I can confirm it's not an American company issue. I'm regularly using my phone as a hotspot for my ipad and whenever I get a phone call the H+ turns into G (2g) and Internet stops working.

Same here. It was like that since my first Galaxy S, it's a technical limitation of network protocols. At least in Europe.

Hang on lets rewind.
Are you in the UK.
The 4G network here in the UK is getting there, But its still got along way to come.
One of them is the ability to pass Calls via 4G.
The problem you have in the UK is 4G is data, While H+ etc is for GSM
The UK have not bought the ability to do both yet.
What should happen, is you will be kicked of the 4G network to take the call, Then be re-connected when you finish the call.
This is not device specific, Its Network Region Specific

The S7E supports VoLTE. It's working on my device. But your carrier has to have it as a service.
Otherwise, you should still have 3G when making a call. If you don't, that doesn't seem right.

VoLTE
In order to make calls and use data at the same time mobile phone networks need to either ...
support VoLTE (Voice over LTE) on the network (Three in the UK is currently rolling this out).
or provide phones with dual antennas, one for voice and one for data (I believe some US networks do this).

No 3G, that's the way normal LTE does works. Just like 2G, because if you make a call under 2G, data connection will be turn off.

Basically it goes down to network support. I never have such problem with 3 UK but work Note 4 on Vodafone sometimes disables data when in call. Sometimes doesn't. Which leads me to believe that it's not just network but also particular towers.

Quick question about VoLTE: Has anyone tested if VoLTE works on the international version (SM-G935F) on AT&T?

I can only tell you that international version supports VoLTE, wherever it'll work on AT&T I don't know.

Each VoLTE network requires a special firmware. There is no AT&T firmware for international s7 edge (still, it might be custom roms supporting this).
I'm in Europe and with international s7 edge I can use voice and H+ data connection at the same time.

VoLTE not working

I rooted my S7 edge, voLTE was perfectly working. But now when I flashed the stock firmware via odin, voLTE no longer works. Please help

Don't know what network your on but here in the UK I think Three are the only network with Volte and it wont work on mine because they said it has to be a Three branded handset............................for now at least, you flashing the handset may be a similar situation

I tried three out for a month and volte worked for me with an unbranded s7 edge duos, trouble is the network signal was awful at home and even though they have the wifi calling app, it doesn't work on a dual sim phone so I left and am now with EE. volte doesn't work on EE with unbranded phone, but I'm 100% sure it works on Three. You have to enable it on your phone though.

It was Three who told me this when I asked why my S7 Edge doesn't work with Volte

OK Mine just worked, it was added to the latest OTA update I received. Don't even get the option for switching on volte now I'm on EE.

Can only connect to LTE and cannot make calls

I have a weird problem with a new SM-G935F (Exynos), which I'm trying to use in Serbia (Telenor), while it's branded for TIM Italy carrier. The device connects to LTE network instantly, but I'm unable to make calls, and messages are received only intermittently - data works properly all the time. When I try to connect to 2G or 3G only, phone cannot register to network at all. I tried flashing multiple modems both for 6.0.1 and 7.0 and tried multiple stock ROMs, after, of course, trying everything with a pristine initial setup...I tested the SIM card in another phone and it works normally. I can't test another nano SIM card with the phone at the moment...Can it be something with the CSC, since that is the only part that I didn't touch? Or is it most likely a hardware problem?
Thank you very much!

I have same problem on a 935f! Up

Hi Sprov,
I see you're from Italy - is your phone also bought from TIM?

It has everything to do with the csc!!
Telenor might be using VoLTE technology to make voice/video calls. Since Serbia isn't in UK, BTU firmware has its own standards and isn't compatible with your region. Same issue for me here. Reverting back to 6.0.1 will gain me back calls feature. Until an official update is released in your region, you will have to compromise this one feature(well the most important one). If you very much want the feature, the only way right now is to revert back to old firmware(including the csc)

Thanks a lot for the insight! But should that affect ability to connect to network when it's set to 2G/3G only? Since the phone doesn't register at all, only to LTE. Thanks again!

This has even happen to me. I was a beta tester to. Recently I added a carrier for my sim 2 which supports VoLTE. When I flashed BTU official yesterday via OTA there was no VoLTE and finally came to know that BTU CSC doesn't provides VoLTE. Since its an unbranded firmware. Reverted back to my CSC MM. Got back VoLTE also.
Waiting for an INS version of Nougat.

It turns out that, in my case, very weird, it was due to SIM card...It worked normally on all modes in 2 other phones, but in this phone only LTE as I stated. Once I put in a new SIM card, same carrier and everything, no problem at all.
I understand the problem with calls and VoLTE, but in this case the weirdest was that it connected to LTE at all, while it couldn't register to network on 2G/3G.

I had it for free, a friend who couldn't stand the problem gave me, though he bought it from someone, not store. Imei is ok.
If i switch from h3g to TIM, so using roaming, i have 2g internet and working connection. Weird.

Wifi calling on freedom mobile

Recently I got an S8 and I ported over my number to freedom from fido.
I thought the wifi is available on S8 but it is not.
Does anyone know when wifi calling would be available for S8?

The S8 supports VoLTE and WiFi calling, however it's upto the Carrier to enable the feature. I'm on Rogers, with my S8 I have WiFi calling and VoLTE working. However people who have unlocked S8's on Rogers won't get WiFi calling or VoLTE because Rogers blocks it on phones not purchased directly from Rogers.

Actually Rogers does not block any phone that it is not purchased from roger's itself.
I have been with Fido for 12 years and last year I got a brand new S7 edge from the Samsung store in Sherway Gardens.
The VoLTE and Wifi calling worked out of the box.
I called Fido and I wanted to make sure to register my new IMEI and the woman on the phone told me that the IMEI is automatically registered after few days
but just in any case she did regestered it.
I kept my Fido for few days before I port my number to Freedom and the S8 I got from Freedom worked in Fido (I unlocked it)
and the VoLTE and the wifi calling. Although what I did was to change the CSC. Then I changed the CSC back to Freedom and I did
not have the option for the wifi calling.
What I have noticed is that the phones that are sold in Canada (At least the major models ) are the same and the only difference is the CSC (network customization)
code that are come preloaded.
Now Freedom is a new to VoLTE and Wifi calling so I am waiting to enable the wifi calling in S8

check this thread, Rogers will not support VoLTE and WiFi calling on phones NOT purchased directly from Rogers:
http://communityforums.rogers.com/t...-Phones-Not-Bought-in-Their-Store/td-p/397684

I don't know what the thread says but I can tell you that I have been with Fido for 12 years and last year I bought from Samsung Store a S7 and after few months an S7 edge
and on both phones VoLTE and wifi calling was working just fine.
I never had a single problem.
Also I called Fido representative and confirmed that both services were configured on my account with a problem
Also few days ago when I got my S8 from Freedom (I sim unlocked it) I put it on my Fido sim card
and VoLTE and Wifi were working again just fine

VoLTE not available for Vodafone

Hi
From the time I bought this phone, I don't remember ever seeing VoLTE working on either of my SIMs (Vodafone and Telstra). Is there anyone else facing a similar issue. Any help will be appreciated. I am on Stock ROM with the latest update as of now of 26 October 2018.
P.S. VoLTE for both the carriers is available, I have checked with other devices and VOLTE works just fine on them.
Cheers

Which country?

I can c....Australia...

Are you able to use VoLTE in Australia? I am in Australia

I am on Vodafone India and I have the same question. Here also Vodafone has VoLTE but the phone is not showing it. But on my phone's settings page there is an extra option "Enhanced 4G LTE Mode". I must add that even after enabling it, I am not getting VoLTE services. My phone has latest build, 334 (but this option was there even before)

Weird I'm also on Vodafone India and I seem to have no problems with Volte it has been working from the start, tho it keeps going to H sometimes and mobile data just doesn't work.

I m also using Vodafone in India but unfortunately Voote is not working although i have checked Enhanced 4g for Vodafone sim but still not available. I am on latest update 334.

Are you guys getting VoLTE in other devices because it is just this phone of mine in which VoLTE is not working either with Vodafone or Telstra. First I thought that it is just the issue with Vodafone but it is not working with Telstra either. I think that Asus has just implemented option for Enhanced Calling on Indian carriers.
Edit. I just updated to latest build but its still not working. I hope Asus adds VoLTE to global carriers as well.
