Trinity data link and lost calls problems - P3600 General

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.

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).
Jörg
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.

Phone connection dropping

My P3600 phone goes insane sometimes, and will not dial out (hangs up immediately after dialing without ringing), or hangs up within 5s of me answering. Does this happen to anyone else, and if it does, what do you change to fix it?
jchap2k
Same here...
I don't know why this happens...
Me also
Running the new HTC official ROM, I noticed it first with the upgrade, I make a call like voicemail from the attention prompt and I put the phone to my head and the call is ended after like 5 sec. I though at first my ear was hitting end but tried it without moving the phone anywhere and it still will randomly end calls right after I try to make them... tried disabling smart dialing and that seemed to work at first but I could have just been lucky because it didn't keep working... anyone else besides us three?
I also lose calls or conversations break in the middle. I went to HTC service and thet recommended me to change the SIM with a newer one. I did that today and I only lost one call so far (but I was sending an MMS while talking to a customer service rep so it might be related to that). If things improve I will let you know.
Mihaig, any news about your SIM change as connection dropping solution ?

I tried turning off UMTS (using only edge), and so far I have not had any dropped calls/immediate hang ups. Would getting a new SIMs card allow me to turn back on the UMTS bands?
I did have a sim card go bad that had to be replaced. The phone wasnt dropping any calls, then all of a sudden just couldnt find the network. My new card has dropped a lot of calls lately.
But i'm not too worried, my service provider thinks its there network fault and I the complete call is free as long as I phone the person back.
Anybody have a 'settings' solution, I would be very interested.

Well, so far no more dropped calls after turning off UMTS. I wonder if a new SIMs card would help in this matter. (mine is only 1 year old though).
Only with Car Bluetooth
There are some gaps in the conversations when I use the Nokia Carset bluetooth but with the P3600 itself no problems so far (just 1.5 week old). I do have some problems with the SD card, ones two days the info is corrupted and I need to format the SD card.
As far as I have found out, the problem has to do with 3G, the 3G hasn't got coverage everywhere ( at least here in DK ) and when the phone switches, it sometimes lose connection for a couple of seconds. Switching off the umts did the trick for me, no more hang-ups or lost connex, but then again, no more video-calls or streaming, so it's a choice... :/
Hope the next update will fix this, if there is a next one... P

There is a known problem with many service providers and HSDPA. If you have the phone on automatic while in 3G mode, when your phone connects to data the phone will switch to HSDPA just for the data transmission (if your provider supports it), during the transmission calls are not received and usually sent to voicemail. This doesn't happen with all providers, but it does with many of them. You can turn off just the HSDPA and not the 3G with this tweak program http://www.fit4cat.de/thread.php?threadid=263. On my phone I have no problems with normal 3G, it is just HSDPA that is the problem.
Hmm, I already tried that program but I still had the same problem even after turning off the HSDPA only. It never happens when UMTS is off completely though. I figure when I want to use the internet I will turn UMTS back on and when I just need it as a phone I can turn it off.
Sorry folks, dumb question: where can I turn off UMTS in my trinity and only have EDGE enabled?
Thanks for your help...
mfg OK
Press the green button to start the phone, then Menu/Options. Select the 'Band' tab and change the upper box to GSM.
Leave the lower box at 'Auto'

I replaced with a new Cingular/ATT 3G sim and still the same problem... I'm going to also try to turn off UMTS to see if this fixes it... mostly I notice when calling voicemail from the notification tab... Oh yeah, it now says ATT as my service...
I have this problem, on the Orange and T-Mobile network, with WM5, and WM6. Have the latest radio, the works.
Bit of a joke that this happens to be honest.. a phone that has 3G/UMTS but that won't allow a certain number of calls when it switches. Pretty fundemental flaw if you ask me!
I've set band to GSM, let's see if it fixes the problem. Will download the aforementioned hack this evening.
Ah, I see it's the operators problem, not the phone's. Flipping amateur of orange not rectify this before shipping..
I've used HTweakC to disable HPSABCD(sic) and will see if the problem stops.
Not a SIMcard problem
HI Guys!
I work in a Mobilephoneshop for a Network Provider, and i had the same problem.
The first trinity that arrived in the shop was mine
And this little bas... droped many calls.
I talked with the tecnics from my prov. first we changed the sim, but same problem. Reflashed Rom same problem.
It has something to do with teh HSDPA, evrytime my trinity connectet them, the calls was dropped, the bad thing was, we have a HSDPA antenna in teh shop
Only the change of the devise worked.
Hope was helpfull and sorry 4 my bad english!
mastah
See above, use HTweakC to disable HSDPA, but leave 3G enabled.

GPRS Issues

Hi
Ive had my Advantage for two days now, and i have missed 16 calls, even though the phone is on and has full signal, after playing around this afternoon it appears to be if there is a data connection active (GPRS) ie active sync live search maps, remote desktop calls get rejected.
Ive had an JasJar for the past year and never seemed to get the issue with that, and im using the same SIM / Network / Number i was before.
Does anyone have any ideas how to get the phone to pause the data connection so the phone can ring?
Does anyone else have the same issue?
Regards
Ben

you don't happens to be using Vodafone do you? If so i know exactly what is going on.....
Nope
No, i am on tmobile UK, what i don't get is that i works fine if i swap the sim back to my JasJar.
Ben
I miss calls all the time, about 70% of my calls fail for some reason or another.
T-Mobile Suck. I never had this much trouble with O2.
I have done experiments where somebody stood next to me calls me, and gets "the number you are calling is not available" while my phone, next to them is turned on with full battery and signal...
Even outgoing calls fail randomly, just says "calling" for ages then stops for no reason.
Ive had not trouble with tmobile since i have been with them (over 18 months) until i got the advantage, ive cloned every single setting i can from my jasjar and still no look, its a shame as looks like im going to have to disable push email!

that is strange, mine one now works perfectly, so when you miss your call, are you on 3.5G( HSDPA ) network or are you on GPRS?

Standard GPRS, it only happens when there is a contasnt data flow if it is just connected and the connection is not being used it calls in fine.
EG if i use remote desktop / terminal services over GPRS then call the advtange at the same time it goes to answer phone, although it does take around 10 seconds before it does though but doesn't ring, like it is looking for a signal/trying to connect.

using the flext 50 with web n walk
I'm in the US using T-Mobile and GPRS and don't have this problem. I'll try to make it "break" and see if I experience the problem but just never noticed it.
If using GPRS and a call comes at the exact time you are receiving data, your call will go to voice mail or unanswered. Its the way the radio is designed...SOme carriers have been successful at ending the data stream and raising the priority of the voice. But GPRS modem in most phones only allows data or voice not both...but,
If using 3g/utms it should ring on the phone. And allow data and voice at the same time.
Maybe you universal is grabbing the 3g signal and for some reason the 7500 is using gprs.
Wu has also reported this problem with Vodaphone and Hsdpa...

that is very correct, i have just change to T-Mobile yesterday, now my HSDPA works perfectly with voice, when voices comes in, it will switch the network to 3G and allow voices to comes in, data is still connected, just lower the bandwidth. Too bad that this doesn't work on Vodafone

This is normal. GPRS and voice calls use the same radio, so when the data connection is active, voice calls won't work. Former co-worker had this (we tested it) with a wizard. He started the data connection, I tried calling his number, and my call went immediately to the voice mail system. There are two ways to change this behavior:
1. Use 3G
2. Use a phone with dual radios

I've never heard of a setting like that. It may be something that your carrier has on it's own version of the ROM, or something that is available on other phones.
I know my wife's hermes will drop the data connection when a voice calls comes in (happened a few days ago with an official HTC ROM), but I've never seen a setting that is changeable.
Try turning on Call Waiting, that sometimes works, depending on carrier.
i get the same problem.its not your phone because it happens to me when am using my n95 on edge.so i just bought a cheap ass phone n diverted all calls to that number when unavailable.at least am not missing any important calls that way..
i get the same problem to when using the tytn too..so i use the same solution

I check but problem is not solved.
"This is normal. GPRS and voice calls use the same radio, so when the data connection is active, voice calls won't work. "
no it's not a phone or general thing it's how modern the central one connects to is
older ones block, newer ones pause gprs while the call is on
newest can multiplex and run both at once and not just for 3g and edge
the fact that you don't get this problem on other operators could be down to two things.
1: the other operators have programmed their networks correctly to give priority to voice rather than data, and so they pause the GPRS and route the call to you.
2: the other networks give you 3G rather than GPRS. this is more likely to allow simultaneous voice and data.
Of course, as rudegar said, it depends on the infrastructure of the operator. I know of many networks in europe where the network is programmed to go straight to voicemail even on 3G/HSDPA. talk about not using the full potential of the technology....

Ah, I wasn't aware of this. So if I understand correctly, if the radio (and stack) is modern enough, the data connection will be 'on hold' while the voice is handled, then pick up where it left off, correct? Or is that handled by the carrier, or a combination of the two?

no the hardware in your operators central which recieve your call
it's not phone depending at all

No phonecalls during sync with Exchange

When being called while the phone is syncing with Exchange (over SSL), no notification is given on the GSM Hero. After the sync, a 'missed call' SMS is received from the provider.
Can anyone reproduce this behavior? It's quite a big issue for my employer, since people cannot be reached in emergency situations now.
This reproduces here both on 1.5 and 2.1. Data connection is via GPRS.
Edit: title updated as it is apparently not a bug in Android.

Hi,
this is not a mobile phone bug, it is a problem with your provider. Modern networks detects that actually a data connection is active, suspends it and route phone calls to mobile phone.
I hope it is described correctly - but, search - there are many better descriptions for that problem in this and other forums.
Greets,
Chr1s
EDIT: If you use 3g you should also available via phone call. I have searched a bit - the network differences declared with NOM1 and NOM2.
Thanks Chr1s, the provider (KPN) says 'data has priority over speech' and they cannot do anything about it.
I will take this through our account manager and also search for this specific issue here. Any other tips are welcome
there is nothing you can do about it, aside from using 3G / HSDPA instead of GPRS

Indeed, I cannot reproduce this with HSDPA. Since KPN guaranteed HSDPA at this location I have something to talk about now...
