[Q] Can't make/receive phone calls when mobile data is active - Verizon Samsung Galaxy S 4

Hi, Hope you can help me solve a problem with my Samsung Galaxy S4 SCH-I545 --
When 4G/LTE mobile data is active:
- incoming calls always go straight to voicemail (the phone does not ring)
- I cannot make outgoing voice calls (it just sits there forever and the call never goes through). If I turn off the mobile data, the call will go through.
When I am on a voice call, I can turn the LTE data on, and everything works fine (both data and voice). I just can't initiate a phone call (or receive one) when mobile data is on.
I am usually also using the phone in Wifi-tether mode, and my provider is Straight Talk.
Please help

Are you using the phone in global mode, LTE / CDMA or LTE / GSM / UTMS? Also, is the phone rooted or have a custom rom?

Global mode, LTE/CDMA
Rooted stock VRUFNK1 (4.4.2)
Xposed framework
It seems now that it's actually a little more complicated than I stated:
Initially (after boot) everything works as it should.
After some period of tethering, the issue appears (no voice calls while mobile data is on). At that point, I have to disable mobile data in order to place a voice call (though I can re-enable data as soon as the call goes through).
Or, if I turn the tethering off, that also seems to solve the issue for some time (even after I turn tethering back on).
I'm using the Wifi Tether Router app, but I'm pretty sure I also noticed this issue when I was using the ROM's built-in hotspot capability (which has other issues).

Try putting it in global mode. I had an issue making calls when I had it in LTE / CDMA. Also, which xposed modules are you running? Which baseband are you using?

How to specify a specific app to always use 4G/data even when on Wi-fi?

For example, I use Talkatone or Sipdroid for my phone calls so I don't want these apps to get briefly disconnected when i connect to a wifi network because i may miss an incoming call. Plus, since voice calls use such little data and I'm almost always have strong 4g signal, it seems like it would make sense to just keep calls on 4g all the time. It's also annoying if i'm at home in a call over wifi and need to go somewhere, then i have to call the person back.
Any ideas? I'm using an un-rooted Galaxy S3 t-mobile currently, but will probably root in the future if absolutely needed when i have the time to mess around with that (and when i'm not absolutely depending on this phone to be fully working following day).
Anyone? I've recently rooted my t-mobile s3. running stock rom.

Call forwarding/ Remote connection method

to get smart relay activated properly you must first turn on the mobile data connection on your phone then the mobile data connection on your watch. if the gear s has auto mobile data defaulted, in 60 seconds you will not have to activate it manually.
This method is to get the calls forwarded. Again, to establish the remote connection both phone and watch mobile data connections must be established. If youre connected to wifi the remote connection will not work.
Once call forwarding or remote connection has been established it is not necessary to keep the mobile data connections on either the phone or watch. The remote setup has been worked out through your cellular provider and there isn't a need to keep data on if you don't need them.
This must be done every time to get it working. I'm using both a tmobile bought gear S and note 4. It all works brilliantly.
if i have the phone and watch connected, and i receive a call, and answer it from the watch, will i speak from the phone? its easier to slide from the watch...
Hello I'm having great problems with remote connection. All I get is error message when I try to activate it. all it says is error has occurred please try again. I have note 4 and tmobile. I'm stuck and been researching for 2 days now. Any ideas?

Redo call forwarding setup both on gear manager and watch itself
Mine takes 2-4 tries to connect but after that its flawless
It has to have remote connection first to do the call forwarding
Any ideas?
A good reset/Uninstall the apps always helps me
Yeah tried. Nothing. Now its not recognizing my sim card
i get the same error forwarding calls when moving from BT to mobile connection. although the watch shows me the notifications, it keeps the error.try again.
how do i redo the call forwarding protocol on both devices?

I am nor completely clear.....are you saying that each time you know you will be leaving your phone at home, you must manually set up Remote Connection and then turn it off when you reconnect to the watch via bluetooth? I thought is was supposed to be automatic. Also, does this Remote Connection require a data plan to allow it to function? I am in Canada and none of the carriers have a "wearable plan". I just purchased a prepaid nanoSIM from Rogers and signed up for a talk & text plan but no data and I don't want to be paying big $ for data if the watch requires data to function with Remote Connection. HELP!

As far as I'm aware there are actually two separate issues to consider here.
1) If you turn on Call Forwarding in the Gear Manager app on your phone, then calls to your phone (using your phone number) will ring on your watch when not connected through Bluetooth (by being forwarded to your watch #). This is simply call forwarding and all you need is a watch plan that allows voice; no data plan required. You would normally use this when you want to leave the phone at home and receive calls on your watch while you're out, etc. The forwarding isnt automatic, you turn it on or off as required in Gear Manager.
2) If you have a plan that allows data (or have access to a wifi connection) then you will be able to receive texts and all notifications from your phone on your watch when connected remotely. You won't be able to receive calls in real time with only a data plan though, unless you also have a voice plan and forward calls as per #1 above. On the bright side, you will still get the missed call notification if your watch plan allows data, so while you can't answer the call you can always call them back right away. Data plans (or wifi) allow for the remote connection to your phone when out of bluetooth range. This remote connection is possible because without bluetooth, the phone and watch can only sync up through your Samsung account, which is why they need some sort of data connection. Once you've set everything up on your phone and watch, the remote connection will happen autonatically within 60 seconds of losing bluetooth connectivity.

Thanks for the clarification. I currently only have the Talk & Text plan so I will have to see how much data is used to push the information. I may have to get a data plan as well.

So to further ask questions about these things..
I just got the watch today and have been searching and trying to find tips on it...
If I am connected via bluetooth.. why does my watch not ring? I thought I could pretty much leave my phone in my pocket all day and do everything through the watch (receive calls and what not). I notice the "messages" app ONLY has messages in there sent from the watch itself. If I get a text message I can view it (not reply..) and it does not show up on the actual watch texts... ideas?
Thanks in advanced.
Hey all,
I just have a question. Lets assume we do have a phone with SIM-A and the Watch with SIM-B. They are connected via bluetooth and for a reason, bluetooth connection get lost. Theoretically, the calls from SIM-A should be diverted to SIM-B. Automatically. Correct?
Because, practically, I am trying this with the Galaxy S7 edge with two sims (SM-G935FD) and it is not working. I got only missed-call notification. The call is not diverted and the phone is still ringing. However, I can do it manually, which of course is not as advertised.

Data while Calling?

Has anyone found a way to use Cellular Data while on a phone call? (Verizon V30 without being on WiFi) I've found posts saying that turning off the Advanced Calling feature does get you 1X data service, which it does, but what about getting full 4G working? Anyone have similar experiences?
Thanks
I've never understood this.
I've been on calls and had emails come in. I've been on calls while using my hotspot with no issues.
So what am I missing?
I just tested mine, on a regular 4G connection here at work. Was able to dial into my VM and listen to all the playback, and then go play around on data as normal. Not sure what the issue might be going on. I haven't changed any call settings (other than enabled wifi calling at home).

Mate 10 tethering doesnt work while on active call

Anyone else face this issue? if you tether the phone internet to your laptop, it works as expected but once you make/receive a call, the internet on the laptop will stop working. I also note that the phone signal will drop from 4G to 3G/H+ on the phone once you make/receive a call.
I have tried to reach out to Huawei for support but not getting any resolution from them.
Issue can be reproduce as below:
1. Tether your phone to your laptop and check that internet is available on your laptop.
2. Have someone call your phone or make an outgoing call, you will notice your mobile signal drop from 4G to 3G/H+. Keep the call ongoing and dont hang up.
3. Check your laptop to confirm that internet has stop working.
Not surprising at all, it's by design and not linked to the fact you're tethering the smartphone's data connection.
Without tethering, use a hands free kit or earphones, make a call or simply call your voicemail and now on the smartphone try browsing or any connected app, they'll fail: data connection is lost during voice call.
In order to keep your (4G) data connection, your mobile provider has to support VoLTE and you must activate related option on your phone. I did it, it's working, didn't try calling while tethering but I'm quite sure it's the same case =)
Still no internet with either VoLTE on and off. And I dont think this is to be expected as my previous phone, Xiaomi Mi Max has no issue and can do both call and tethering at the same time. And my colleague just did a test with his new Samsung Note9 and also didnt face this issue. Not sure if this is a software bug or a hardware design flaw/limitation
I use tethering/hotspot every few days and didn't notice any problem. Signal drops from 4G to 3G because Mate 10 doesn't support VoLTE but internet works fine for me.

Please test tethering while on call, not just tethering alone. Tethering alone works fine for me as well.
Internet will pause during phone call unless your network is VoLTE. My phone network signal will change from 4G to H+ during phone call.

As I said, it works fine while on call. I use tethering in my second apartment, airports and in almost every caffe bar and didn't notice any network problems on my notebook if someone calls me. There is one lost packet when phone starts ringing and that's it.
The first photo is WiFi hotspot + phone call and the second photo is USB tethering + phone call.
Hi Guys,
Thanks for the input on VoLTE, base on this info, i query my telco (Starhub) regarding this, and just a few mins ago i received an SMS that "HD Voice Plus" had been activated for my number. HD voice plus is just what they call VoLTE. Now i have a VoLTE icon on the top left of my phone. I tried the same case again and sure enough it is working now. Cheers.

Question Issue with voice calls being incomprehensible when WiFi calling and Verzion 5G/LTE are both active on Verzion P6

I'm having issues with voice calls on my Verizon Pixel 6. I live in a wooded area with not great 5G/LTE reception and rely heavily on WiFi calling as such. I had no issues with my P4xl. After upgrading to the P6, I am having constant issues when I receive or make a voice call to a friend or family member.
Their voice becomes echoed and incomprehensible. Sounds like you are talking to a robot.
The only workaround I've found so far is to disable the WiFi manually in the settings while you are on a call. Then I am on the network (either 5G or LTE) with not great reception - one bar.
I have a feeling it is an issue between the WiFi calling hand off and the network. I've tried adjusting the setting in the developer options turning off Mobile Data Always Active. No luck.
Also changed my WiFi preferences to Use Device MAC and that did not help either.
I'm concerned because if someone else needed to use my phone in an emergency, they would run the risk of not being able to make a clear and successful call.
Any help appreciated!
