,
I am facing a problem related to 3G data connection.
The problem is as follow, while having a talk (voice) many times the data connection (3G/H) drops due to some reasons and never re-established until phone call is over.
I found this to be very annoying, if no phone call been done the data connection is perfect 99% of the time but doing voice call disconnect the data (both 3G/H) and never re-established until the phone call is over.
Once the call is over, the data connection resumed (3G/H indicators shown)
Please advise
Thanks,
Because the voice call needs your connection to the operator and that's why the data connection is terminated while the voice call is active.
Happened to me on every phone (LG KU 990, Samsung Omnia, HTC Desire).

You are correct but...3G/H supposed to allow data&voice in parallel, and sometimes is does work such. But once the data connection terminates it never re-established until voice is over.
You are right, but not at all operators, just tested ORANGE SK with HSDPA signal... drops after a voice call is beign made.
BTW, are you GSM or CDMA?
Just learned, that if you are using a custom ROM, can make this problem. Also are you set to WCDMA preffered in the *#*#4636#*#* menu?
GSM
yes - WCDMA is set
Network type - UMTS
Is it just a case of the icon disappearing during the call? Try starting a download whilst on 3G/H/E connection and then make a phone call, switch to the market and check to see if the progress bar is... progressing (excuse the pun!), if it is then data is still active. If your on a GPRS network, data would be disconnected for the call.
So, I keep my wifi on mostly at all times. But I've found that when I leave my home, and get outside my wifi range, instead of naturally switching back to 3G (I usually have 4G disabled for battery purposes, unless I need speed), my 3G and bars icon will be all greyed out, and I will have no incoming data. I otherwise have a great signal here in Boston. Sometimes it will eventually start working, but other times I will need to reboot in order to have a working data connection.
Is this an issue anyone else has? It seems the transition from wifi to mobile data is glitchy?
So when I'm on wifi in my house, my phone appears to switch to edge or something and I lose most connectivity (goes from 4 bars to none). Enough to initiate a call, but simple head turning will cause me to drop. If I turn off wifi, I get 4G back and full bars and no dropped calls.
Wifi calling is too inconsistent to rely on, and this basically makes my phone unusable. I don't want to keep wifi off, as it's a lot faster and I only get 2.5Gbs of high speed data to use a month.
I'm also in the middle of a major city with great coverage 4G coverage, as long as I'm not on wifi....

If you go into your wireless settings, you can uncheck Wifi Calling so that if you do connect to Wifi, you will retain your regular amount of calling bars.

I appreciate the response, but I've already had wifi calling off.. because that feature was basically useless (could not rely on it ever).
My wife Note3 got the same problem, set cellular network preferred and then turn off wi-fi calling. Lose all cell signal bars. When no cell signal, caller ID became funny, like 718-123-4567;oli=63 212-123-4567;oli=00, had no idea.
My own note3 had the same setting, but everything fine. full cell signal bar. Try to google it, no glue!!!
Then I returned my wife note3 and get another one, everything fine.
I had the same problem. When I was on wifi I had no signals. I got a new sim card and the problem is now gone.

i dont think thats the issue, and why do you care because if you call someone it should be able to call and once you need to switch back to tmo it will w/o issue.

Uhh... it certainly doesn't switch back to t-mobile without issue. I drop the call. I haven't had a single call work the entire time while leaving my wifi on in my home.
Clearly, when it's on wifi, even if you have wifi calling turned off, it switches to some other network specifications, which appear to barely work where I live. The problem likely lies in the fact that when you turn wifi calling off, it does not switch your cellular network preferences back to normal properly, Instead, when wifi calling is off and you're still on wifi, it just doesn't route things through wifi, but doesn't actually change your mobile network settings back properly.

well here's a question do you leave mobile data on even though you're connected to WiFi? As i have no problem because i have bars even when connected to WiFi because i leave mobile data on and have WiFi calling turned off. even if WiFi calling is turned off, and i turn WiFi off it switched to T-Mo network in seconds and i'm able to call someone so yeah no issue. you clearly have a problem with something or its the network where you live.
i'm not trying to be rude but it just doesn't make sense to me that you're having issues with something that shouldn't be a problem.

I do leave mobile data on, all the time, continued issue.

This doesn't actually work currently on the Note 3. there is a bug where any time you have wifi on the cellular entenna turns off regardless of the state of your wifi calling on a very large number of Note 3's. Lost Soul clearly hasn't been reading on the threads here. there are many on this topic. We get that you don't have the issue LostSoul, but that doesn't mean it isn't an issue.

Thanks Hughes,
I have found that when it enters that state, that if I go and turn wifi calling on and then set it to mobile-network preferred, it turns the cellular modem back on, at least for a little while. Can you point me in the direction of a more robust thread where others are discussing the issue?

I had the same problem on stock rom. Flash wicked rom earlier this morning, signal bars now showing bars instead of no bars on stock rom. been testing it all day long, signal bars still showing. Didn't change any settings. Just disable wifi calling.

I've flashed a rom as well and it appears as it might be fixed... hope so.. my phone is useless if it can't function as a phone while on wifi.
I had same issue. Called TMo and had them unregister my wifi calling, and got bars back immediately. I had wifi calling turned off, but it seemed to be the default regardless. I could only receive and make calls with wifi turned off...but it all works fine now.
That didn't work for me

I called Tmo four times and asked them to unregister wifi calling. They said that it wasn't even turned on for my account then that it doesn't matter what is or isn't turned on. The phone is going to run calls, text over whatever wireless connection it thinks is appropriate. When you have a strong wifi connection, it chooses that connection regardless of wifi calling being turned off or on. I set the wifi calling preference to cellular networks and it still does the same thing.
I'm pretty pissed off about it. Anyone fix this?
Not true. I shut off Wi-Fi calling on T-Mobiles site and bars came back. Had the exact same problem.

Hello,
I'm using two swedish providers in my phone - 3 and Telenor. Both are capable of LTE/UMTS, I'm using 3 as the primary provider for all options in the Sim settings and the Telenor one only to receive calls.
So I recognized a problem where my data connection would drop when the 'open wifi'-notification popped, I tried to disable that and it seemed fine at first. However I'm still getting data connection drops when me phone swaps from LTE to UMTS(3G/H/H+), no errors are thrown and I'm only seeing it due to no data loading within apps or disconnects in-game, the display isn't dropping the coverage indicator nor the indicator for which network is being used(3G, H, H+, LTE, 4G+). After some time the data connection returns but keeps dropping rather frequently once this pattern starts.
Airplane mode restores connectivity for a while (I haven't clocked it) but eventually the connection stops receiving data and the disconnecting pattern returns.
Calls and SMS are working as far as I've noticed so far.
Any ideas?
Edit: I've restarted the phone multiple times.
Any one got similar issues or any fix :3?
Anyone else facing a problem of lost data connection during a call? It happens even even with wifi connection. I sometimes need to use the internet during a call... but the internet connection automatically disappears for the duration I'm on call. As soon as I end the call everything is normal.
When on LTE the phone automatically switch to 3G/UMTS during call (VoLTE is not supported by much providers yet).
During the switch if you're in a bad 3G area or with many people on your cell data connection is lost, the phone gives the priority to the call obviously. LTE is working very differently so that's why you can have a nice LTE data connection and without moving a ****ty UMTS data connection.
I've managed to browse web during my calls without issues on the 5T.
