Issue with Voice calls while browsing in 2G (T-mobile) - Desire General

I am using HTC desire (T-mobile UK) for past 28 days. Most of the time my friends tell me that they are not able to reach me. They get the message something like not reachable.
I did not know what was the problem initially. But finally I found that the issue was when I browse internet. At my office I only get '2G' signal inside the office building. The problem is when I am browsing internet in my office (using the available 2G signal) then I cannot receive any voice calls. Who ever try to call me while I am browins in 2G will get a message "*** The mobile number you have called is currently unavailable please call again later ***"
This problem does not accur when I browse internet in '3G' or 'H'.
Is this the issue with T-mobile network or with the HTC desire phone.. please help.. Thank you

my phone is in wcmda only mode, so i would not know about that problem mate... I will try it out on gsm only and see what occurs

Looks like you've just been given an answer over on the t mobile forum. Quoted from 'Chippy':
This is a limitation of GSM/GPRS. If you have a PDP context (GPRS conection) but *no* activity is occuring i.e. no data transferred at that specific time, then someone should be able to ring you and the connection will just be suspended while they do. However, if the GPRS connection is active at the time then the channels needed by the the network to page the mobile are in use and the person calling will get an engaged tone. This a perfectly normal limitation of a 2G network and not a fault of either the phone or the carrier. Do you not have W-FI at work you could use?

Try putting your phone into WCMDA mode only and see if you keep a good enough reception to warrant its use

Tmobile is set up to reject calls when the GPRS is active. You will only get a call when on 3G on tmobile. Vodafone is the only operator in the UK that drops data to take the call on GPRS.

I never knew that. Now all those missed calls on t-mobile makes sense now. where I work has poor 3G service and I guess with so much syncing now there is more chance of a connection being active when a call comes in.

new HTC user here having a weird problem

hey guys
ok so i have the TP2 running WM 6.5 professional
ROM 1.86.401.0 (67102) WWE
ROM date 25/9/2009
radio 4.49.25.17
protocol ver. 61.44tc.25.32U
my service provider is Etisalat in the UAE
the problem that im having is that when i set the BAND to AUTO, it picked up the the 3G network...but problem is that it keep shuffling between 3G and EDGE. because of that it wont recieve calls. one fix i was told was to manually select GSM BAND. the call problem was solved because of that.
but since i have done this, i been having another porblem. after using internet to say update the weather tab, i cant make or recieve call, or send sms or anything. everytime i use internet on the TP2, i have to switch to AIRPLANE MODE and then back to PHONE its driving me nuts
anyone facing the same problem? or has a fix to this?
Switching between 3G and Edge is normal, because not everywhere you have good service.
But just to make sure:
When you set band to AUTO and you are switching between 3G and Edge, can you call someone?
I had problems with my HTC Kaiser in the UAE. Etisalat and Du told me they only can provide mobile internet to BlackBerries and IPhones...
yeah, when it is switching between 3G and Edge, i cant make calls and i cant recieve calls either. they say my cell if off while its actually on

Go into the Bands page (where you manually select the bands). Press "WCDMA" to enable 3G only. That will keep you in 3G, but if you go into a non-3G area, you won't get any signal at all.
EDGE can only handle one thing at a time. If you don't have an active data connection, you can use the phone (call, SMS). If data connection is active, you can't use the phone functions. So, if you're on a webpage and someone calls you, their call won't go through.
3G allows you to use phone functions and data at the same time. So if you're on a web page and someone calls you, you can answer it.
ok that was surprisingly simple.. thanks
Edge can only handle one thing at a time? I routinely get and make calls and browse at the same time (or get emails via active outlook push connections, etc). And this is both when I'm in Edge areas (eg when I go to my cabin in Montana (heck - ANYWHERE west of Milwaukee) or when I have 3G (around here).
This does, however, appear to be a feature strictly of AT&T. But I don't believe the inability to do simultaneous data and call is a hardware or even Edge technology limitation - I believe its a network specific limitation.
Having said that, my money would be on an incorrect radio or DLL hanging around in the phone...
(Standard disclaimer: I know nothing about non-US carriers or their oddities. I reserve the right to be wrong- a right I exercise somewhat frequently )
well i upgraded to WM6.5 so the radio is the one that came with the upgrade.nothing else has been changed.
have a feeling the problem is with the phone as my pervious phone, sony ericsson's P990i had absolutely no porblems switching from data to call and back to data without having to do anything.
one thing i noted is that once i start an internet session, it keeps running unless i turn the switch to airplane mode to force a connection break.

Orange Desire dropping calls and diverting calls to VM

It seems to have got worse over the last few days. At times I need to make more than one attempt to dial out, the calls drops unexpectidely, and people who ring me sometimes get redirected to Voicemail even though my phone is on with good signal. Have phoned orange multiple times about it, and after diagnosing with them, still at a loss. Anyone else expereincing similar?

P.s. the phone is not rooted, however very recently I used ADB to install all apps to SD.
oh, the phone has also rebooted a few random times on it's own aswell over the last few days. I think it's all linked.
Have inserted the sim card into another phone. On my desire, while testing, out of 8 incoming calls, 2 went to Voicemail. On my other phone, out of 20 incoming calls, 0 went to voicemail. Seems that it's a fault with the phone and not Orange reception. Going to phone HTC.
Suggested I do a hard reset. I might aswell root my phone and install stock if that is the case.
Any suggestions before I waste a day?
All my previous devices, were on orange, the service was awful, texts coming hours and somtimes days late, calls going str8 to vm, slow data ect, when i got my desire i changed to tmob, and ive never looked back

Hi
I used to have an X10, that frequently put peoples calls direct to VM in full reception (even with a mate standing next to me calling it went to VM). Now i have the desire and still the same issues, I get random texts telling me I have missed calls when the phone never rang. So I'm not sure if its Orange or Android. I was previously on o2 and didn't have these issue
Update the radio part ?

I know that, but in my area, i only just got gprs with orange, but with t-mobile i get an excellent hsdpa signal, and there cheaper, £5 for a months unlimited internet

If you are on GPRS (i.e. no 3G coverage at your location), and you are actively using the GPRS connection (including for background data), then it will block incoming calls as if the phone were in a call already. This is a limitation of GPRS*, and it is the same on all UK networks and all phones.
This doesn't happen with 3G/HSDPA, or if you are using Wi-Fi for your data.
I don't know if this is the OP's problem, because it shouldn't cause dropped calls once established (or affect outgoing calls, I think) but it is the effect behind what some of you are describing.
*technically, it doesn't happen with certain GPRS devices (class A?), but there are very few such phones, and there are certain network measures to avoid it, but no network uses them.
so if somebody could write an app that suspends data connection if on 2g and allows data for 3g only, then problem solved?? Obviously only for people who are not really bothered by loss of data sometimes.

I'm always on GPRS party because there's no 3G/HSDPA at home nor at where I work. So I've hard-set the phone to be GSM only and I've never missed a called so far. Even had calls come in mid facebook usage....
Edit; Tried it again now,
Box standard non-branded desire, Orange Pay As You Go.
a G icon to the left of my reception bars.
I was updating the weather widget both Up and Down arrows where lit up.
Rang from my office phone to my desire..No problems at all.......
my data connection is usually switched off (saves battery), so that isn't the cause,

Odd. Maybe Orange changed something - I've never tried with them. The network feature is called DTM, but I didn't think anyone had turned it on. I frequently miss calls on O2 because of this.
The Desire also appears to frequently lie and reports the wrong symbol much of the time - so at work with only GPRS (in the middle of nowhere and we have our own cell on our site), mine often says H for HSDPA, and yet the same problem occurs. I suppose it's possible that you're actually on EDGE.
There's a thread about it here: ht tp://androidforums.com/htc-desire/68995-not-receiving-calls-when-browsing-gprs.html
used to have this problem with my x10 on orange until i flashed a new rom and updated the baseband, hasn't dropped a call since....... the wife recently upgraded her phone to desire hd and she is now having the dropping calls/forwarding to vm problem. i reckon its got to be something wrong with the radio orange are using, get it flashed and see if it helps? that is my plan with the missus phone!
I had this happen with my phone on o2 on 3g I notice my signal bar wasn't high though an drops easily. One day i got loads of delayed msgs an calls going straight to vm. I switched my setting to use 2g only an now no problems.

That's the same work around i have been using. 2G also seems better for battery life, so now I prefer it over 3G.
OP - my partner has been experience EXACTLY the same issues as you with her AMOLED Desire.
To the point where we are possibly going to root it soon, in the hope that a new ROM/radio will resolve the issues. Not sure how viable this is though...

No network when network is "G"

Hi guys!
I have a strange problem with my One X. When my network is on 3G/HSDPA i have perfect internet. But when i'm at school, i have only G network. The problem is, when i'm on G network (full signal bars) i have no internet acces, no google talk acces, nothing!. As soon as my network jumps to 3G/HSDPA i have network access again!
I don't know what the problem is. But i guess you people can help me out!
Thank you very much!
Edit: I also tried to reboot, airplane mode, mobile data on/off. No go!
could be just because gprs is so slow and sucks so bad, that everything is just timing out?
try forcing the phone to use wcdma only when you're at school, then it might have just one bar signal, but that'll still be better than gprs.
i have to do that at work to be able to stream videos in the car park lol. otherwise it simply doesn't work.
Haha allright! Nsh it worked yesterday lol. Maybe something to do with sim card?
Sent from my HTC One X using XDA
could be a network outage possibly (i work for a comms company, and we get notifications for o2, used to get orange and vodafone notifications as well for when the networks go down, or having maintenance, and they do have lots of problems)
could just be they're either doing maintenance or the local mast is having a problem with 2g.
if it worked fine before, i'd try calling the network provider first and reporting the issue, they may well advise new sim, but i doubt its the sim if the 3g is working and 2g isn't, sounds like a network issue.
I take it you've tried rebooting your phone?

Text/call problems on 3g only

Hi,
Does anyone have any ideas on a specific problem I have with the One X (on t-mobile - sim only contract in UK)
Had the phone since it first came out and the last 6 weeks I've been unable to send or receive texts while the phone is in 3g (wcdma mode or wcdma/gsm auto). The only way I can receive/send texts and calls is in gsm mode. I've been on the phone with T-Mobile for over an hour making sure my service centre number and network operator is correct and I have no signal issues (mostly full signal).
I've tried turning the wi-fi off to see if that's an issue but it makes no difference. What's weird is that in 3g (wcdma) mode I have no problems with data, so I can use the internet/facebook/twitter apps and upload/download pics and files just fine.
The engineer at T-Mobile (android dept) told me there's a 3g and 2g antenna in the phone and the 3g antenna may be faulty. Sounds plausible but wouldn't that mean no data connection on 3g too? I've also been told to check my micro sim in another phone, which I'll do when a friend comes round (I don't have any other phone that uses micro sims).
I just thought I'd check in here to see if this is a known issue. I've googled and nothing's turned up with this particular problem. Normally it isn't an issue as I use wi-fi for data so just keep the phone in gsm mode. However, when I'm out I swap to 3g sometimes and forget to swap back. I had two days worth of missed calls and texts when I forgot to switch back this weekend :laugh:
In summary:
gsm mode = texts, calls and internet all working fine (though slow data connection, obviously)
wcdma = no texts or calls but internet fast and working fine.
Any ideas, help or advice would be appreciated. I don't want T-Mobile saying it's a phone problem and HTC telling me it's the network's problem.
The same problem here using a WWE model (no carrier) in Vivo Mobile (Brasil).
No solution until know...

No internet when I'm on voice call

Hi folk, so I've something strange: when I'm on voice call (make or receive) my network change from 4G to H/H+ and internet doesn't work. When call finishes, network go back to 4G and I'm able again to surf internet.
I called my mobile company, Vodafone IT and they told me it's a phone problem (they don't use VoIP) so I contacted Google assistance but since my phone is magisked they can't help me.
Any idea?

This is a normal behavior and has nothing to do with your phone or Magisk: If your carrier does not support VoIP, the phone has to switch to 3G or even 2G to make the phone call. After the call has ended, it switches back to LTE.
I know that this can be a PITA, especially when you are supposed to take part in a Skype or Webex meeting with screen sharing and you are sitting in a hotel with bad WIFI. Then you use the phone as WIFI hotspot. As soon as you call in, your web meeting is unreliable.
Been there, done that. There is no way around this, the only thing which works for me is to take part in the call via my notebook instead of calling in via the phone. Then LTE stays - as long as nobody calls you
@BabelHuber thank you for your answer.
But why this happens?
Why isn't possible to have call and 4G/LTE at same time?

Because the LTE standard simply does not support voice calls.
Hence if you don't have VoIP, the phone has to switch to 2G or 3G. The alternative would be not being able to perform voice calls at all!
