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?.
Riz
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.
Can I have 1 sim for data & voice running at 4G, while the other sim for voice & sms only in 3G? Or only 2G supported?
Because I read at 1+3 forum that it can actually do this, so I was wondering if the Axon 7 can as well. I don't see why not, correct?
Has anyone tried this? I'm in the US, and would like to be able to run a tmobile mvno sim (4G+voice+sms) + an international sim (voice+sms) that's roaming on AT&T who will shut down 2G soon.
It's a dual 4G sim slot, so yea you can run it like that.

Go to settings - dual sim settings - network mode and on sim 2 tell it GSM only. It will keep sim 2 on 3g. Also on settings -dual sim settings you can turn off mobile data for either sim. Just put t-mobile in sim 1 and at&t in sim 2, shut off mobile data on sim 2, and tell sim 2 gsm only. Done
Thanks for the info, I didn't buy the device yet; but this makes choosing a device even harder since both can do this now (1+3 & Axon 7).
Until recently this was NOT the norm I believe, best I could find was a dual sim phone with 1 sim @ 4G while the other @ 2G only.

Doesn't GSM-only mean 2G? While both slots are hooked up for 2G/3G/4G, I think only one slot can be connected to 3G/4G at a time, the other slot goes down to 2G.
When I have my Verizon SIM in Slot1 (chosen as data connection) and a T-Mobile SIM in Slot2, using apps like LTE Discovery show my A7 connected to Verizon LTE, Verizon 1x (2G for voice calls), and T-Mobile GSM (2G), not T-Mobile HSPA (3G). When I switch the data connection source to Slot2, it connects to T-Mobile LTE and Verizon 1x (2G), not Verizon EVDO (3G).
Yes I was able to confirm LTE and WCDMA simultaneous operation
Hi! Amazingly, yeah this works...you can have LTE on one SIM and WCDMA 3G on the other (voice only). I tested this with two T-Mobile SIMs and was kind of shocked as in the past it seems like all dual-SIM phones are limited to GSM-only on one of the two SIMs, as has been mentioned above...
But...strangely, this won't work when using a CDMA SIM in slot 1 (i.e., Verizon). I have no clue why...I can definitely confirm that my experience is the same as that stated above by xtermmin - the GSM SIM will be limited to EDGE (2G only) when the CDMA SIM is active as the data SIM. But with two GSM operators yes one can be LTE/WCDMA and the other can be WCDMA/GSM. I'll confirm real quick just to make double sure but I seem to recall seeing this in the specs and was able to confirm it myself. I've attached a screenshot showing this - I have SIM 2 enabled for data as you can see but SIM 1 still shows voice-only on UMTS and thus is not just limited to 2G. I hope they fix this phone so that CDMA SIMs will have this same functionality...for now though I can say confidently that two GSM SIMs can be operated as LTE/WCDMA on primary SIM and WCDMA/GSM on secondary SIM simultaneously...really great news considering all the EDGE networks seem to be on their last leg!
EDIT: Oh - and don't mind the fact that the "Cellular Network State" is shown as disconnected - in slot 1 I have an old T-Mobile SIM just for this test - it isn't active at the moment on an account. But for demonstration hopefully it does suffice as it definitely has the phone connected to 3G service on SIM 1 while having LTE service on SIM 2. Also - I've included a 2nd screenshot to show that with Verizon LTE/CDMA on SIM 1 (shown as carrier '123456'), SIM 2 will be limited to GSM-only on T-Mo...really weird - not sure why this limitation exists for CDMA users - I think it's a ZTE bug as simultaneous CDMA 1X and WCDMA is possible with T-Mobile as the data-SIM.

Yeah for sure...I love the phone and all but I really hope ZTE will just fix these annoying CDMA bugs already...Seems like they could fix this stuff with or without Verizon's approval - from the beginning they've kind of hamstrung CDMA and I've never really understood why. Another bug I noticed was that when switching calls to the T-Mobile SIM, VoLTE has to be kicked into gear by toggling the VoLTE toggle and sometimes even putting the phone into airplane mode for a second...from what I've heard this is a unique problem to CDMA use as well.

Thanks for the info. Has this issue been sorted out to your knowledge? We livein 2 different regions, but would only consider getting the Aussie release of this phone this month if it can seamlessly handle 4g/3g, using 2 SIM cards where both are capable of LTE. Will this work? Does it automatically switch data to SIM 2 in order to take 3G voice call, or does it temp. disable data on sim 1 (4g) to allow SIM 2 call?

Hi - I just tried this and here's what I found:
If active data is on SIM 2, a call to or from SIM 1 is possible on UMTS (WCDMA 3G) but this will terminate the LTE connection on SIM 2 for the duration of the call. However, a call on SIM 2 will not be a problem for data unless SIM 2 is on EDGE or less...on UMTS or LTE (i.e., a VoLTE call) you'll still have data during the call.
If data is on SIM 1, a call to or from SIM 2 is only possible on EDGE!!! I didn't know this! I guess SIM 2 will always be GSM-only if SIM 1 is the active data SIM. And also - you will lose LTE data on SIM 1 if you receive or place a call on SIM 2 EDGE/GPRS.
So...it looks like the situation isn't as good as I'd hoped - if 3G calling is necessary on a particular SIM card at all times, that SIM should be placed in slot 1. And it'll work well even when SIM 2 is the active data SIM. But, if you need 3G calling at all times on both SIMs, you may be out of luck.
Also, the Axon does not seem to allow you to change the data SIM in the middle of the call...in this scenario, SIM 2 was on LTE and was the active data SIM, and SIM 1 was on UMTS (calls only). I made a call on SIM 1 and then changed the data to SIM 1 to try and get 3G data during my call...but it didn't connect to data until I hung up the call...so it seems that the service state gets frozen when you make a call, in a way.
I hope this info helps...seems like kind of a mixed bag, unfortunately.

Thanks for the. That's pretty backwards by ZTE. Makes no sense. SIM 1 and 2 need to work the same way regardless of WHICH SIM had the 3G incoming call and which had 4G data active at the same time. I read the above as SIM 2 can be 2G only, or is the main SIM for 4G data....so 3G calls can be taken on SIM 1. Yep, backwards!
Axon hasn't sold me. Audio on a phone is important, but the HTC front facing speakers get easily clogged, then it looks horrendous. I'm favouring one of OP3T (as i believe this too has unlocked bootloader and root), or worst case - LG v20 or G5 dual...but neither will be given unlocked bootloaders.

So, I just tried it again and it looks like I was able to achieve a UMTS 3G connection on both SIMs even during a call on SIM 1...perhaps my initial test was in error somehow...not sure. But it looks like dual 3G is possible after all...there may be hope!

Are you sure both are running 3g, because I have had devices that always showed 3g even when connect to 2g networks, really need to test with an app the can see both sims at the same time like network cell info mini.

Yes I'm sure. I was using LTE discovery and the Settings --> Phone Status...not just the signal type indication. It can run dual 3G UMTS and/or HSPA+.

Sure thing. Just to make double sure, I just put my FreedomPop (AT&T) SIM in with my T-Mobile one and set both to WCDMA...And it's confirmed that dual 3G works fine (see screenshots below). So you should be ok! AT&T has decommissioned 2G completely so the fact that I could sustain a dual T-Mobile/AT&T connection when T-Mobile is active for 3G data should hopefully prove that the Axon 7 can get dual 3G. One caveat though - with a Verizon SIM in slot 1, slot 2 is still 2G only...So you will be limited to 2G in slot 2 if you have a CDMA SIM in slot 1 which is data-active. But two GSM SIMs should be ok. Good luck!

So Awesome, does anyone if the same is true for the new ZTE Blade v8 Pro, I sure hope so as I am looking to add both of these to my collection, Using prepaid H2O wireless for calls and text and FreedomPop LTE or Global sims for data... What would be the best setup for that data ( FreedomPop ) on sim 1 or sim 2. H20 is a AT&T MVNO

The only limitation vis-a-vis SIM 1 vs. 2 slot I know of when it comes to GSM SIMs relates to WiFi calling... You can only get WiFi calling on SIM 1. But that shouldn't matter for FreedomPop or H2O I would think so it shouldn't matter. Also, CDMA SIMs only work in slot 1 but of course that should affect you either. So either slot should be fine I'd think!
Hi,
I have a Moto X pure 16GB (xt1575) bought from USA. I used it on multiple carriers in USA and it worked fine.
I am on a visit to India, where I intend to use the phone for couple of months.
I tried with these networks:
CDMA sim (Operator Tata Docomo) - Network gets detected and sim is operational
GSM sim (Operator Airtel) - Sim is detected but doesnt get registered onto network
GSM sim (Operator Reliance Jio) - Sim is detected but doesnt get registered onto network, seems some problem with Jio network, they have additional things for VOLTE to work.
So, I am pretty sure, the handset is fine, changed the network settings thru the secret menu phone info, to LTE, GSM to what not. nothing works for Airtel Sim.
The bands do work in India and are compatible.
Any idea's what more can I do?

It does show the Apn, but the gsm service shows as unknown and network type as unknown.
Any users from India have any suggestions.
AIrtel and Jio work fine on the Moto X since many users here have and are using it with them, except the VoLTE part of Jio you have to use the Jio4voice app to make/receive calls.
Have you tried going into the Phone app, dialed *#*#4636#*#* and gone to Phone Info and changed "Set preferred network type" to something different?
Also, I think the Jio SIMs require a very specific registration process, going through several apps to get them working... check with a local shop.
Here's some snapshot from the menu screen and network finder applicaton.
I know the ans to this soln
i am a jio user and basically the problem is that mxp supports volte but the frequency is the main issue.. due to unmatchable frequency the volte ain't activated for jio
u can try t&t and Verizon sims volte is working on them but jio frequency is not up to that mark as mxp but an official nougat update might help the frequency to maintain and volte might get activated.....
so we need to wait for official nougat update only... trying romcwont work..

After switching back to Android 9 it now says "This is currently unavailable under the call settings for Wifi calling. I am at a loss. I live in an area were the cellular signal is spotty at best and need Wifi calling to work.
Anyone have any ideas?

AT&T doesn't like unlocked phones so it's possible the option isn't showing up because of that. Many AT&T customers with unlocked phones have reported that they needed to contact AT&T customer service to get WiFi Calling or Volte working.
