[Q] 318: no data during call? - Streak 5 Q&A, Help & Troubleshooting

I was on a lengthy call last night, and found that during the call my 3G/GPRS/Edge data didn't work (wireless did).
I thought he GSM/3G phones were capable of keeping the dta connection while in a call? Is this operator dependent (SingTel in this case)

Sounds like you were already on wifi when the call was placed. Why would data work if wifi was on?

Can you Please Post Questions in the Q&A Forum Thanks
Moving to Q&A

No, wifi was of when the cal started, so my profimail used cell daya to connect.but while in the call that failed, until I turned on wifi

Tested again today. I started the call while on Wifi, then turned that off, and cell data did not allow any connection to go out. bummer.

[Q] mobile network state disconnected

ive been using the phone for a few weeks now and it was fine until today, i cant connect to the internet via edge . ive tweaked with all the settings but nothing seems to work. everything else is fine . ie i can make calls and send text's but i cant connect to the internet. i checked under the status and it shows the mobile network state is disconnected. i have no clue as to wat this is since im new to android.
pls help!
Have you turned MOBILE DATA off via the power on/off menu .
jje
ive checked that too.
Go to Settings- Wireless and Network- Mobile Networks- Access Point Names and see if the APN is ticked or not or the correct APN is ticked.
everything is back to normal again,it connected to the internet, by itself . must be a random bug in the os
problem solved. peace
I have experienced the same thing with my phone, except that it shows "activated". After a while it just started working again.
I've had the phone for a couple of months now and everything has worked fine till now, a little bugs here and there but no issues. A few weeks back (on android 2.3.3) I was unable to make or receive calls, but surprisingly was able to make text messages. I tried everything, turning flight mode on/off; the phone on/off; etc. I was on the verge of contacting Samsung but then suddenly the thing started working once I came back home from the office.
There has been no problems till then but today suddenly (now on android 2.3.6) the outgoing calls no longer work, same for outgoing text message; but I still get incoming calls and messages.
Just to be sure that this wasn't a SIM or service issue, I tried changing SIM's (different SIM did not work on the phone) and used my SIM on different phone (where it worked).
Also 3G doesn't work as well, but connection here is spotty so I wouldn't trust that. The only message I see different on the 'About Phone' tab is 'Mobile State-Disconnected'. I have full signal strength and all that.
My thoughts are that it was, or rather is a phone specific issue and would appreciate someone else's thoughts on the matter. As to my problem I assume it will sort itself out in a little while.
FYI: Samsung Galaxy S2; Android 2.3.6; NOT rooted; Indian version; On Airtel Mobile Network.
Mobile network state disconnected.
Hi guys, I have the same problem with my network connection also my 3g does not work anymore, I`m play with some secret codes like a ##72786# on my epic 4g touch sprint phone flashed to metro pcs and now I have no 3G service. In the setting menu under network status say Sprint. How can I get my 3g back?. The mobile net. 3G is on and the wifi is off. I need to change the network to metro pcs in the status setting and how can do that? Thanks for your help and sorry for my bad English.

WiFi calling.

While in Mexico next month can I WiFi call to the US on my g3 ?
I have the HTC One (M8) and did my update (Which added the Wi-Fi calling app). I am currently in Mexico (Been here since Saturday) and I couldn't get the Wi-Fi calling to kick in while connected to a Wi-Fi. Everytime I tried to connect by enabling the Wi-Fi the location part of the Wi-Fi calling app would kick in and I would get a message something to the effect that wi-fi calling wouldn't work in my current location (Not exact words but that is what it would tell me). So I decided to turn off the locate me feature in the Wi-Fi calling app and enter my home address (from the US) and it said confirming address took a while and it seemed like nothing happened. A little while later all my text messages and my voicemail s started to show up on my phone and the Wi-Fi calling icon showed up on my status screen.
I'm going to be honest. I was also tinkering with the network connection settings and manually selected cdma/lte in the network mode and enabled Domestic voice and data. I just wanted to get some type of service (i didn't care if it was going to go into roaming because I needed to make calls back to the states). So I'm assuming I am using the Wi-Fi calling feature because I don't have the data portion on the phone turned on and I don't have international voice or data enabled. But I will find out on my bill next month.
If I'm really on Wi-Fi calling mode then the key (i think is to trick the location servive of the Wi-Fi calling app to think you in the US by typing in an address in the US and not letting the app locate you automatically to Mexico....
I was trying to upload screen shots from my phone but the web browser let's me. I will pots the images after the 19th..

I just returned from Mexico and had turned the wifi calling on my last day their. At first worked great made a few calls back and it worked crystal clear. Then it started to ask for location I tried everything even when it did accept a location over the border in the U.S.(I was in a border town) it stopped working. My friend who has the wifi calling from T-mobile had no problem. Hopefully Sprint (lol) will get a clue.

Mobile settings - impact on voice calls / reception

Hi, sorry if this is a frequently asked question. I have a new edge and was originally on a 3g sim only plan and all was well. Last week I switched to a 4g sim only plan (BT Mobile). Since then the reception around my house has been really poor, and voice calls almost impossible.
Looking though the settings the only difference I saw was --> Network mod, changed from to WCDMA/GSM (auto connect) to LTE/WCDMA/GSM (auto connect)
If I change this setting back to WCDMA/GSM (auto connect), voice calls / reception in the house if fine (but now 4g is switched off for data).
I don't understand how to trouble shoot this. BT Mobile confirmed good 4g out doors, poor indoors for my address, but I don't understand why voice calls are not so poor. Please could anyone assist in explaining why the phone behaves this way and if it is a hardware fault or perhaps just a software / deisgn issus
Thanks

Can't make calls and no mobile data

Hi there,
I have a Canadian Galaxy S6 edge .
I am with Telus and the APN settings are correct. It shows t that I am connected to 4G sometimes , yet there there is no internet and I cannot make calls.. Sometimes I am able to make a call but then signal cuts and and I cant make calls anymore. I am able to receive SMS. and wifi works.
I did factory reset and it didnt change anything.
I just bought this phone from someone, and I didn't really have issues yesterday. The only difference between yesterday and today is that I used Samsung's wireless charger to charge the phone....
Anyone can help? Mobile network si set to GSM/HSPA/LTE
Thanks

VoLTE call beginning chopped off when wifi calling enabled but cellular preferred

Can anyone out there see if they get the same behavior as me?
I'm in a band 12 area, with a 4 bar LTE signal.
Wifi calling is enabled but CELLULAR PREFERRED, I'm connected to the T-Mobile ASUS router on Verizon FiOS (2.4, 5ghz, doesn't matter).
Long press 1 to get into your voicemail. What you expect to hear:
"You have no new messages in your mailbox..." is chopped off and what I hear is:
"mailbox..."
If I turn off wifi, the issue goes away. If I turn off wifi calling, the issue goes away. If I change the wifi calling setting so that it uses wifi preferred or always (so the call is an actual wifi call), the issue goes away. If I force the phone to use HSPA, the issue goes away.
So even though the call isn't a wifi call, something about wifi calling and wifi, even though the call goes through VoLTE, is causing the start of a call be be chopped off.
At this point I have disabled wifi calling on my phone.

I have the same set up, I'll turn off WiFi and report back, as I've noticed the same issues...

My theory on what's happening here is this:
While you're telling the system too use VoLTE and setting cellular preferred, it's starting the call on Wi-Fi calling and handing off to VoLTE.
The reasoning it's simple...when on Wi-Fi, cellular data is deactivated. VoLTE depends on cellular data. When you start a call, it establishes it via Wi-Fi calling, and establishes the cellular data connection. Once that connection it's up, handover occurs, but this causes a few seconds of Audio loss because it has to set that back up.
You can see the delay yourself by turning off Wi-Fi, then turn off mobile data. Turn mobile data back on and you'll see the delay between enabling and being reconnected too the LTE network.
Hope this helps explain the issue. It's a handoff delay caused by having to reconnect mobile data and LTE, and you likely wouldn't notice for normal calls, but VM answers immediately.

I understand what you're saying and thanks for the explanation. And I realize that when wifi is on, data is going through wifi and would have to switch to LTE for a call. So this does make sense to some extent. But.... if wifi is on but wifi calling is not, the calls happen quickly and are not chopped off. But the same holds true - the data is going through wifi and would have to switch to LTE. Your reasoning explains it for wifi calls always and wifi calls never.

That's because with wifi calling ON, the call is initially set up through wifi calling, and has to hand over once the mobile data connection is up, LTE is negotiated, and VoLTE is negotiated. If wifi calling is OFF, the call is established via GSM, then (optionally, but not usually) handed over to VoLTE once LTE is up and VoLTE is negotiated.
I've done work in the industry with VoLTE, and my day job involves VoIP, so it's not as simple as one might think. Believe it or not, GSM to VoLTE handoff is much easier than WiFI calling to VoLTE. It still explains it, believe it or not, it's just a matter of which path. It's also harder to hand off from VoLTE to GSM when you roam out of a VoLTE area... which is the primary cause for VoLTE call drops.

Why haven't they implemented that then? That hurts them in the rootmetrics etc. scores where they'd test phone calls.
For example, band 12. You make a VoLTE call, drive to out of range of LTE and the call drops to HSPA or Edge. It nevers goes back to LTE. So when they're doing their tests, if the call switches away from LTE, then they drive to an area that is band 12, when the HSPA signal gets weak, the call gets dropped even though there's a great band 12 signal.

Back to my original point though - what I'm hearing is that this isn't unique to the V10. I'm wondering why this isn't all over the internet where people are noticing that the start of their phone call is missing when wifi calling is enabled but they've set it to cellular preferred (which is NOT the default BTW).
