[Q] T-mobile Data turning off during a call - myTouch 4G Q&A, Help & Troubleshooting

I noticed when i am on a phone call, the E or H(aka data tmobile data) turns off while i am in the call and disappears. Then comes back after i end the call. Does anyone else notice this or know how to make it so it stays on even during a call? Also, when wifi is connected the data service turns off?

First off this is normal when your in a 3bars or less 3G/H area. Your phone will switch 2G while on a call if the 3G signal gets low but it won't switch back until the call is ended. Also on 2G/E you can only do one at time, voice or data. T-Mobile's 2G network is stronger than their current 3G network also.
So if your on a call and the H disappears, this means your phone has switch to 2G/E because your 3G/H signal was low. You won't see E on a call since that would be data and 2G can only do one at a time.
If you want to force 3G/H then goto settings, wireless and networks, mobile networks(I believe) and select WCDMA only under network mode. Please note that if you go into a non 3G/H area you will loose complete signal and your phone won't switch to 2g.
and yes wifi disables mobile data.
Good luck.

Hero, have to choose: Data/3G or voice calls, HTC reinvet the 90's!

Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.

Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.
Cheers,

i have sprint as well and when someone calls you when youre running hybrid, you should not miss calls. you will get disconnected from the internet when someone is calling though

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!
You actually use mms?
Wow, they do exist.

What NOM1 Networks are there in the UK? I only get 2g in my area (booo) and could do with an operator that works right. T-Mobile forums suggest they still have an issue
Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?

Loosing 3G While on Calls -- ATT HSDPA

Has anyone experienced this before? I seem to loose 3G connectivity while talking on a call. I can keep talking... but the 3G icon disappears and I see an alert icon notifying me that I've lose data connectivity.
This doesn't happen all the time, but quite often. Sometimes, the icon with signal bars will have a small 'R' at the top left indicating that I may be in Roaming mode.
I've got the ATT Nexus One with Bell Mobility as my carrier (Canada). They have a pure HSDPA network with no 2G fall back, so I'm not sure how I could lose 3G and still be on the call... I've got 2.2.1 FRG83 with Stock Android and the phone is NOT rooted.
Any suggestions? Should I reapply FRG83 -- or the entire stock android image (is this even possible on a non-rooted phone)?
Not sure if this is the same, as I never go into Roaming mode... but I routinely lose my data connection while making phone calls. I'm on T-mobile, btw.
Is this something normal? Have you just ended up living with it?
I'm slightly concerned about missing an email or SMS during a call if data connectivity is lost. Although, I don't think that data is truly lost as Bell Mobility only has a 3G network, there is no 2G to fall back on...
Are you sure you're not roaming over other networks? I'm sure you are switched to another network, and the data is dropped because Android has a switch to turn off data (which has nothing to do with SMS, by the way) when roaming, and this switch is on by default.
When the data is dropped, I believe it's not re-negotiated until the end of your conversation, so if you're switched to a roaming cell tower for even a second - your data is gone until the end of your call.
If your cellular carrier has agreement with other carrier's cell towers and they accept roaming (which is sometimes the case, as I've learned from this forum) - you should turn that switch off to retain data even when roaming.

Stuck on 2G after calls

Using N9005, I've noticed that I get stuck in 2G after making/receiving calls. On very rare occasions, I'll be on 3G after the call, but usually I just get stuck on 2G for long periods after that, unless I go into Network Settings and toggle it to WCDMA to force it out of 2G, then toggle back to LTE/WCDMA/GSM.
Alternatively, does anyone have any way to completely disable 2G?

Yeah 4G does not work on call it will go to h+ or 3g or g it should take about a minute to back to 4g or whatever it was on, all phones do this

Yes, I know, just that it seems to be very rare that my phone is on 3.5G or 3G after ending a call.
Taking a closer look at the 3G reception in my office (pretty much the only place I make/receive calls), I realize that the spottiness of the 3G reception could be making my phone choose 2G over 3G. Guess I have to test this out somewhere with better reception.

How to favor 3G over 4G when signal is weak?

I have discovered that my MXP consumes more battery than it needs to over night. This is because, on my night stand, I have strong 3G signal, but weak 4G signal and the phone hangs on to the weak 4G signal consuming unnecessary power, even though I have good WiFi too. If I manually select my 'Preferred network type' to 3G in settings at night, this works, but I can't automate the process of setting 3G or 4G modes.
I discovered the "test mode" (dial #*#*4636*#*# on the phone keypad) and the Phone information section allows you set many more options via the Set preferred network type drop down. I'm unclear what the different options option will achieve. I want the phone to prefer 3G over 4G when the signal is poor. Is there an option for this?
Phone is stock, unrooted, on the EE network in the UK
3G = WCDMA
WCDMA PREFERRED (prefer 3G)
WCDMA ONLY (it will turn off you 4G and 2G.)
thing is if the phone shows it is hanging on to a weak 4g signal you have to remember just because it is displaying a weak signal it is still connected to the stronger 3g signal, it has to be otherwise you wouldn't get calls and texts.
Will have to experiment, but
> WCDMA PREFERRED (prefer 3G)
Does this mean it won't connect to 4G at all if 3G is available?
> if the phone shows it is hanging on to a weak 4g signal you have to remember just because it is displaying a weak signal it is still connected to the stronger 3g signal
Maybe, but my issue is the power consumption when connected to a weak 4G signal
Silly thing is it's not necessary to maintain a connection to 4G at all when WiFi is active, when the only useful benefit of 4G is fast data
If a phone is connected to a weak signal, it will take greater toll on battery.
Try - settings, more, mobile networks and then preferred network type. You can then set 3g?

I want the phone to automatically prefer 3G over 4G when the 4G signal is poor. Doesn't look like this is possible, and I'm stuck with aggressive 'hanging on to' 4G despite heavy power consumption.

Calling not working in LTE

So I use my sim on roaming and I have been facing this problem that my calls only work when I set mobile network to WCDMA or lower which hence reduces my data speed coz it's 3g. What to do?
4G (LTE) services is a data-only service, and does not support voice (unless it is voice converted to 4G data or VoLTE), hence whenever you're dialling or receiving a call network drops from 4G to 3G. Happens to me all the time on roaming, sometimes even on home network with poor VoLTE connectivity. Nothing to worry about.
