Phones does not work when dat connection is active

Hello Everyone,
I am having a wierd issue with my HTC Tytn.When my Data connection is active I cannot make or recieve phone calls.Any incoming call goes straight to voicemail and any number I dial the phone will display "call ended" before it even starts to to ring. The minute I close the data connection the phone works again.I have updated my ROM to the latest English ROM.Could my unit be defective?
Thanks in advance!!!

Hmmm that's weird.
Your TyTN is acting as class C device (Data or Voice), and in fact TyTN is class B device (Data is suspended while on Voice).
Is your unit defective? Possible, but... first backup your TyTN completely, then re-update full ROM, set up data connection and call to check it while on active transfer. If it will be OK - your unit is OK and this is software/registry problem, if not your unit is might be defective. This is the quickest way to determine.

My device does this as well, but only when connected to Slingmobile.
Other "always on" programs are not affecting me.
Not sure if this helps or not Just trying to add more data.

data causing call dropouts
Hi,
Hope this helps, but here in Australia when using the Telstra HSDPA network on UMTS850, when i'm connected to a data session, I can't receive calls and the caller gets the "phone is switched off" message. If I force the phone to use the old UMTS2100 network, the phone will pause the data session and allow the incoming call. On another forum I have read that this is due to a limitation in the Ericsson 850MHz hardware which the telco is using on their mobile towers and they expect an upgrade to fix it sometime in January. I don't know if this is 100% true, but it is what i have read

If I have a data session in progress it gets disconnected whilst a phone call is in progress (I can receive calls fine, although I have had one or two occasions when people have rung me and it's gone straight to voicemail without notifying me of the call). After I hang up, the data session is reestablished.
Using T-Mobile in the UK for what it's worth.
This is a very weird issue, sorry I can't offer any more info or advice.

I'm on T-mob Flext WnW and have the same issue. When I have my data connection established (either gprs or HSDPA) anyone that tries to call goes straight to voice mail. I can make a call which temporarily stops the data session and then re-establishes it after I hang up.
Is this a known issue on T-mob?

In the HTC faq, it is meantioned that the handset is a GPRS class B device:
http://www.europe.htc.com/support/faq.html?id=119
This means that the data-traffic is suspend for voice calls.
http://www.gsmworld.com/technology/gprs/class.shtml
(I haven't tested this with my HTC, but my Nokia 6260 did behave like this)
The HTC faq also states the full 3G operation ought to allow for simultaneous voice and data calls. I personally interpret this that calls are possible together with a UMTS connection (but I could be wrong).

For all with problems with connection while on data.
Most of us here have no problem with it, might be network you are logged, not fully compatible with class B.
My advice: check different phone (TyTN) if same occures, if yes then different handset (other brands). If it still is happening - call network and demand some explanations and upgades.
Still supporting my first post to hard reset device and check if without all software you have same problem.
And for the record - most of mobile operators calls this "Ring-through problem"

JUST FYI
Cingular says that for some reaosn streaming data (for my my slingbox) will not interupt. So phone always goes to voicemail.
Once I get the higherspeed data in my area this problem should go away.
This was posted by another in response to my question, and also confirmed when I called Cingular. Although it is possible we were both misinformed by support.

Incoming calls not received when online

I'm sure I've read about this problem in the past but I can't figure out whether there is a way around it. My model is an MDA Vario II in the UK. Is there any way to avoid missing calls when the phone is connected to the internet?
It's great having a phone with internet access, but not so great that it doesn't seem capable of functioning as a phone at the same time!
thanks

Can anyone help with this please?
thanks.

Am I really the only person with this problem, or am I just being really dumb with my forum searches?
thanks

I think there is a difference between GPRS and UMTS. When a GPRS connection is active (at least, when data is sent or received) you are not able to receive calls. When UMTS is active, calls should get through. The standard way should be that the device detects an incoming call, shuts down the GPRS connection and restarts it after the call is ended. With UMTS, the device can receive and send data and answer the call at the same time. I have actually never had any problems with unanswered calls while browsing, but I use UMTS all the time (or perhaps no-one is calling me while browsing).
I have no idea what fault in your phone could cause your problem. Try searching with better keywords perhaps in the future, I found several threads relating to this problem by using the words "data connection missed calls". Use the same words for a search and I am sure you'll find lots of threads about this.

This will always happen with any handset. if you are sat there reading a page and not loading any data then the call will interupt the GPRS connection then reconnect once the call has finished. If you are sending or receiving data then the person will get a busy tone. Sorry this is just how all the UK networks work.

Trinity data link and lost calls problems

Hi all
I am wondering about the purchase of a Trinity. Someone, on an italian forum, has posted the problem of incoming calls lost (the caller receives a busy line signal or the phone results unreachable) while the phone has a data connection active (apparently only an HSDPA one). Has any one observed a similar problem ?
Thank you everyone.

This is standard behaviour when transferring data over 2G GPRS. It should not happen on 3G. I have received phone calls while using 3G data and the phone rang as normal.... I can't report about HSDPA (is there a simple way to check if HSDPA is actually used?)

No, it's not, voice calls always have higher priority even in 2G networks.
Can someone else confirm this issue with Trinity?

Well.... it's the third time in a few days in this forum that I post something and I am told that I am wrong. The previous two times in the end I happened to be right, so according to statistics I should indeed be wrong this time!
However I think I might be right this time too! The standard behaviour with GPRS sessions is that they are interrupted when they are idle and an incoming call is received; if data is being transferred then the phone will be busy.
Obviously for outgoing calls the phone will stop the data session when you want to make a call.
(All this for GPRS on GSM)
PS: You don't believe me try to use a GSM phone as GPRS modem for a PC, start a large file transfer and try to receive a call.

Well, since I use GPRS internet for more than 3 years actively and have changed a couple of phones already I must say that GPRS system is projected in a way that voice calls are priority in any situation. In this years I have found that sometimes my phone is not reachable when I'm connected to a GPRS but that percentage is rather small, could be some other problems related to a base stations.
In your case I would think of contacting your operator, change phone or just change a carrier, being unreachable during GPRS sessions is something that I will characterized as bug, at least. NHF

You are right. It was a very common bug in the early Class B GPRS phones and I thought it was supposed to be like that, but indeed even a class B device should suspend the data session and ring when a call is received.
However I am reading in other forums that this is now happening again with HSDPA.... the joy of early adoption

I had some strange behavior like a busy signal when I had my phone set to 3G only, but I think it was because of marginal reception. I changed the frequencies to automatic and haven't had any problems since.

Hello hawk971,
I have the exact same experience while being persistently connected on the Swedish HSDPA network (Hi3G) I cannot receive or even make calls, most of the time. It's like i can sometimes manage to "slip through" with a call, and even an incoming call can get through if i'm lucky. I have figured out that if i end the data connection and make the call, i can re-login with the connection and keep babbling on the phone.
The problem started to appear right after we moved to a different area where HSDPA is deployed, at first the problem was very sproadic, but now the network is growing, so does the blocked calls.
Luckily i get an sms from the 3 network saying that someone has tried to call without leaving a message, otherwise i'd be clueless.
I have considered contacting 3 operator to discuss this, but i reckon i might loose the HSDPA access then because i have only 3G subscription but somehow my phone (which is purchased without operator lock and not from 3) snaps right onto the HSDPA access nevertheless. I have a consistent 1Mbits/s DOWNLINK and 350kbits/s UPLINK connection while running TPTEST on the laptop and using the P3600 with internet sharing and USB-cable.
I so would like to be able to stay on the HSDPA but right now i am considering to drop the high-speed since the phone part is basically rendered useless. I am also using GpsGate in the car, so my internet is always on, transmitting position, i guess that makes the problem worse. I might have to drop that...
I had a friend told me he had the same problem with TyTn and Hi3G here in Gothenburg. That makes me think that there's no particular problem with my phone. Rather it's a network problem that they yet have to solve.
Anyway, that's a long post!
P.S. Does anyone know how i can disable/enable HSDPA on the P3600 easily?
Cheerio

just remove link to "enableHSDPA.exe" in \windows\startup folder and soft reset you phone.

I can't find this file (enableHSDPA.exe) anywhere in my P3600....

Bump!
SecureGSM can you please elaborate a bit on this .exe file. I have a standard HTC P3600 and I don't see this file anywhere in the file system.

i'd like to know how i enable HSDPA on my HTC P3600. has anyone had success doing so?

I recently installed the fit4can or HTweakC as it is now called from here
http://wiki.xda-developers.com/index.php?pagename=Hermes_Registry. It allows you to turn off HSDPA and do other tweaks to your Trinity. No harm is done since you can turn the HSDPA back on again anytime. Since I upgraded to the new 1.38 Radio, I was picking up HSDPA all the time at home, and every time my phone was auto checking email I'd miss calls. This HSDPA "feature" needs a little work.

receiving calls while online (edge) with wing?

Hi,
I have a t-mob wing (after I drove over my magician and I have the following problem: When I am having an active data connection I cannot receive any voice calls. The calls are going directly to voice mail, without notifying me. Once I stop the data connection I can receive calls again and than I will see that I missed a call.
I talked to t-mob support, and after doing a hard-reset (of course) they told me that this is a known problem with the wing, that they are trying to fix it and that there is nothing they can do right now.
1. do other wing users in the US experience the same, so is it the default behavior, or am I just unlucky? (it worked great without a problem with my magician btw)
2. as sometimes during the day the internet connection automatically gets connected (activesync I guess) I never really now if I am able to receive calls right now. Is there a workaround to manually start up and stop the internet connection without the device automatically connecting whenever it feels like it?
thanks in advance
wolferl

interesting ...
I have had a lot of complaints from people telling me that when they call me, it goes straight to voicemail.

I'm also a US Wing user, and I can confirm that is happening to me as well. Was checking sports scores on my break at work earlier, and my girlfriend called me, and I got a voice message from her...but it never showed that she called.
I also have the issue with people in my fave 5 not showing in the call history anyway, so I guess I lose both ways.

hm,
ok, seems to be a generic problem. Is here anyone who successfully gets voice calls while on a data connection with a wing/herald/p4350?
would be interesting to see if it is a t-mobile or device problem.
thanks

I got a HTC wing and i still get incoming call while browsing the internet. No problem here. i've tested a couple times and they all went through. I have T mobile

hi hondaman,
thanks for the info. whats your provider?

"active" data connection is the key
I have the same problem, no voice calls with an active data connection. For me, it seems to be only when the data is actively transferring, like streaming audio or a largish download. Straightforward web surfing doesn't seem to cause the problem, I've received multiple calls while surfing. But during streaming audio, calls go to voice mail every time.

I swear to you, I get calls when I am using data all the time on my Wing. I have the stock T-Mo rom and everything. No CID unlocking, no SIM unlocking.

It happens to me alot that people complain they have called me and it goes straight to voicemail... and its been in cases where im not even using my phone, and as far as I know, I have good signal.
I was running this GB soft program that kept my data connections always on... so I stopped using that to see if I notice a difference.

On the T-Mobile MDA it worked just fine, but on my Wing I can't receive calls while online either.

I just did some testing and I need to correct my original statement. Looks like kerrkj and the others were right. Just being online does not stop you from receiving calls. Just when you are transferring data, the line being actively used, you are not reachable. So, when you are web browsing, it depends whether the moment the call comes in, data is transmitted or not. I was testing accessing different web pages and a couple of times it worked and a couple of times it did not. When streaming audio the calls went to VM 100% of the time.
So, when I am using tomtom and having the traffic check activated, it will be pure coincidence whether you receive a call or not. When streaming audio it will be guaranteed that you are not receiving calls.
I am pretty sure that it was not like that with my magician. Hopefully t-mobile sorts it out sooner than later.
thanks for all your feedback
wolferl

it happens to me too, i know on sprint with the treo's you can run internet or phone, all calls will go to voicemail if you are on the internet. i just assumed it was that way with all of them.

Can't receive calls while listening to internet radio?

I searched around and was unable to find an answer to this.
When listening to streaming radio either through Last.fm or streamfurious I can not receive phone calls? If anyone calls me it goes directly to voice mail. As soon as I stop internet radio calls come through again.
Does anyone know of a way to fix this?
Thanks in advance.

If your not on 3G then it is because you are using all of your 2G service. If you use 3G then you can use it for data and internet and 2G for texts and calls.
Someone correct me if I am wrong.

Bleh, wrong thread. Delete plz!

Not knowing exactly how our phones carry the signal for internet and voice calls that seems like a logical answer to me. Huge drag for me though I love turning on internet radio in the car and piping it through my system. Even on 2g it sounds and streams great. But the lack of not receiving calls I suppose I will have to stop that habit lol. Who knows when 3g will roll out in my area...
oh well. Thanks for the info.
Doug

It's true that it's impossible to use data and voice at the same time on 2g, but it's the app that should pauze itself for an incoming call. Or Android should have been able to do this! Atleast that was the case with my last phone. While checking something on internet, call display appeared on incoming calls and browser disappeared. Call ends, browser reappears.

Well maybe it is something that just has to be change with the current internet music streaming software. I have tried three different ones and they all do this so it doesn't look good for a pause feature when a call comes through.
I have no idea how hard that would be to add to the current software. I suppose if you had 3g you wouldn't worry about this but as we all know, T-Mobiles 3g coverage is lacking.
