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?
try the fit4cat regedit program

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.
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.
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.

may i ask is there any reason why you are not using 3G? GPRS tend to have this problem, but 3G won't.

Coverage, my house and my office don't have 3G coverage, else i would be.
i was on o2 b4 n hardly ever had 3g signal n when i did my video calling never worked....since moving 2 t-mobile ive had no problem....my data connection is mon 9 till 6 b it 3.5g, 3g or gprs n i use cortado.com push email service for instant emails.....i still receive calls when connected
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

there is no solution, the only thing you can do is swap your operator, or just don't use 3g at all....
I am using my Touch Dual for one week now and i must say i really enjoy it.
However I had a problem that while calling sometimes my phone would just end the call.
First of all i thougth that my ear was pressing the screen, casuing it to end the conversation so i installed slideactions, and slide to unlock.
Tonight i had a phone conversation and it end the call 4 (!?) times!
After the first time it stopped the conversation i made sure my ear was not touching the screen but still it stopped the call.
Does anyone have an idea what could be causing this? I really like the phone but i absolutely hate it that it quits my calls alot!
Kind regards,
Montezume
I get the same problem. I find it happens when the phones trying to change between 3G and GPRS but still when I turned off 3G I still get the problem its really anoyying. What operator are you with? Im with orange there pretty dam poor for coverage.

Cause they are terrible! Especially where I live.
My provider is Hi.
I use Nodata to turn of all the other connections, how can you turn of the 3g mode?
go to start>settings>phone>band>and select gsm mode
hope it works!
Might be a stupid question but what is the difference between 3g and Gsm?
I never use any internet connection so there is no need to have 3g turned on, or does it also have affect on normal calls?
3G is for fast data connection, and videocalling.
So if you use neither of them, it's best to just use gsm.
3G has less coverage than gsm, and more important: i't reduces battery life greatly

Cool, thanks for the explanation.
i changed my network type from auto to GSM.

Hello all,
I have had my X1 for about a month, and it seems I've come across a problem that defeats the purpose of a phone. I can't seem to receive calls for some reason...recently my friends and family have been telling me they have tried to call me but it just ends up going to my voice mail. I just tell them I was probably on the phone with someone at that time, or my phone was off. Only today did my friend call me to find me in a parking lot that I finally realize its my phone. So I attempted to call myself with my homephone, and tada! it went straight to voicemail. I don't even get any sign of a missed call.. Did anybody else getting this problem? I did a soft reset and it seem to fix the problem. It has probably happened within the past 2 weeks..I have the generic UK rom so I'm still waiting for the official R2A one. It would be great if someone could explain how to prevent this problem from happening.
not that i have a problem with my x1a, mostly because i rarely get calls and rarely use it but i have another phone that would have a problem that you describe.
i think it was due to the phone switching between 3g and edge signal. i work in the ship yard and the steel walls around the ship interfere with my signal and my phone would switch back and forth between getting the best reception (3g and edge).
well anyways, i think the switching back and forth would somehow screw my phone up and i wouldnt get any calls after getting off work.
my brother who also works at our shipyard and carpools with me would try to call me up to ask me if i was getting off in time but i wouldnt know that he had been trying to call me untill we meet up. he tells me that he has been trying to call me and so as were walking back to the car, i asked him to call me to see if my phone is working.
sure enough, my phone doesnt work untill i turned it off and then turned it back on. so if your in an area with poor 3g reception, maybe that could be causing your problem.
my old phone was an old lg cu500. thats my beater phone and since i dont use it for browsing the internet anymore, i set it and leave to use edge. it gets a stronger signal than 3g but if i do need to use 3g, i just go to my phone settings and set it back to use both signals. for some reason, i almost love that beater phone more than my xperia. mainly because its small, compact and i dont have to worry about scratching or damaging it anymore.
hmm, that is rather interesting...however my service provider's 3g frequency band is not compatible with the x1. I also don't have an internet service type of plan with my phone.
However just going to my settings, I noticed that my phone was set up to attempt to connect to the internet via HSDPA. I'm going to disable it and see what happens.
if you dont have 3g or hsdpa connection, then i would set your phone to use only gsm.
I also miss most of my calls but my problems is other some times it rings and some times it doesnt. Anybody know how to fix this?.
I have seen these problems with another PDA, in that case it seemed to be related with the PDA radio at the beggining, but even if that is one of the probable causes, there are another two to be considered.
The first one is the sim module, I own the same sim since 6 years ago, and this sim was programed specifically for the symbian phones of those years, it is in fact unable to send/receive any MMS with a PDA.
The other PDA I'm talking about is an Universal, the same phone worked ok with my sim and failed to receive many calls (even if the covering of this phone company was "better") -in the same place- with the universal, We first suspected a broken sim, but using this sim in a old gsm phone, it worked just fine.
Also, the cell companies, tend to "abuse" of their position and then to "seed" the phones with applications that do use the phone automatically, these programs are made mainly for symbian phones.
Remember also that the cell networks are exactly that, computer networks, and sometimes their databases are not perfectly compatible with all the possible variations of slightly different phones, in this case, PDAs are the least common type of phone.
So, try your phones with other (another cell company) sim, try using the sim with old phones, etc.
hope this helps.
