Calls possible with HSDPA Data Transfer?

Hi all
I experienced some problems since I upgraded to WM 6 (official Tytn Europe Version)
If there is a active Datatransfer in HSDPA Mode, i cannot make or receive a phone call. I already tried several Radio Versions (1.43/1.48/1.50), but no success. When I disable HSDPA, it works fine.
Does anybody has same issues with HSDPA?
Thanks
Marc

Vodafone issue
Hi - are you using a vodafone network? I know that there are issues on the network that are preventing some operators from supporting voice and data at teh same time over HSDPA....
The operators I know about are planning network upgrades or patches to solve the issues (which are not just limited to Windows Mobile devices apparently)

I can make calls -> versions below I don't think this is just a phone issue though. I think some operators can't do it.

I have the same problem as you have.
It is because of the infrastructure of my provider KPN that I have this problem. When I disable HSDPA then all works fine. So no I only use HSDPA when I want to browse on the Internet.
****ty but now I know why.........

Hi all
Thanks for the confirmation.
I also disabled HSDPA for now.
Now I will the push the guys in the network department to fix this issue......
Just got the answer from the tech guys. Operators with Ericsson UMTS/HSDPA Network Equipment are affected by this. The Operator has to rollout a software update to fix this issue.
Cheers
Marc

I am on AT&T and have never been able to do data and voice at hte same time.

I'm on At-T in Nyc and my HSDPA works just fine calls while on data and vice versa

I'm in South Florida and I'm constantly using Internet Sharing in HDSPA mode while talking on my Jawbone... (takes "jawbone of an ass" to a whole new level, ehehehe!)

OK, now THAT is the funniest thing I've read here! Thanks for the laugh!
I saw the jawbone at the ATT/Cingy store and wondered if I should splurge on it since I already have an H500 and an H700 from Motorola. My problem is I ride bike a lot and the wind noise makes it impossible to have a conversation with an H500. It is possible but a little difficult to talk while riding using the H700. I was wondering if you had any experience with the Jawbone under similar conditions?

OOPs - That was meant to be PM, sorry folks!

The Hermes is able to do both. Phone calls and data (HSDPA\GPRS\EDGE) at the same time. Your data speed does take a hit due to bandwith.
However if you cannot is because is 99.999% the network NOT the phone. I had a Hermes long before the network here in Canada supported HSDPA. So I could only do one at the time. At the beginning of this year they finally updated it and I have been doing both at the same time with wild abandon no problem.
Check with your provider.

@gmgonzal - the Jawbone will probably be the best you can find for your enviroment. I only use it in my Toyota when driving. People can't tell that I'm on a cell phone. I had a NxZen which I liked for a while but this is better, IMO.
@agovinoveritas - indded, that's the biggest reason I upgraded to the 8525... no more missed calls when I'm using the internet (or receiving an email at the same time..)

It's the network. All operators that use Ericsson 3G equipment suffer from a bug in the Ericsson kit that prevents simultaneous data/voice. All Nokia equipment works fine. T-Mobile in the NL use Nokia and have no issues. KPN and Vodafone NL use Ericsson and have this issue. KPN are currently upgrading their Ericsson equipment to correct this issue (ETA end 2007). I do not know about Vodafone NL. It is safe to assume that in other countries these providers use the same kit so you should be fine with TMO, regardless of where you are.

Does this issue include that my telephoneconversation can be disconnected?
I had this problem with the WWE WM5 HTC rom using the Vodafone NL network. Now I have uograded to the Dopod WM6 ANZ version it's all fine...

Questions about band setting

I live in the UK, and am using a foreign version of a TP2 that I bought on eBay. I think it's probably the Hong Kong version - it's in English, but with support for Chinese characters on the keyboard.
Something I do fairly regularly is switch between 2G and 3G modes on my TP2 manually. I've created a start-menu short-cut to CMBandSwitching.exe which lets me change the phone's Band setting between "Auto", "GSM" and "WCDMA". My somewhat limited understanding of these settings is that "GSM" basically means "2G", and "WCDMA" basically means "3G". When I set the phone to "GSM" it picks up GPRS or EDGE signals (according to the status bar). When I set it to "WCDMA" it picks up HDSPA or 3G signals (if there are any). What I thought "Auto" mode did was simply switch automatically between 3G and 2G mode depending on 3G signal strength - so that if there's a 3G signal it uses that, if not, it uses 2G.
However, it seems like there may be slightly more to it than that. If I have the phone in GSM mode at home and search for available networks, it finds O2, T-Mobile, Vodafone and Orange (in that order - does that mean O2's signal is the strongest, or does it put it at the top of the list because I have an O2 SIM?) In WCDMA mode it only finds O2, which would suggest that O2 is the only 3G signal that can be picked up in my home (and even that's pretty weak ). However, if I set the phone to Auto, then search for networks, then it also starts to get a signal from the 3 network and lists all 5 carriers - in other words, in Auto mode it finds a signal which is not visible in either GSM or WCDMA mode. This suggests that Auto may be doing something else besides switching between 2G and 3G. Can anyone explain this?
Also, if O2 is the only network it can find when set to "WCDMA" does this mean that O2's is the only 3G signal I can receive?
Finally, there are four possible frequency settings in the lower part of the BandSwitching app. These are:
Auto
GSM(900+1800)+UMTS(900+2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
Which is the best setting for UK use? I'm currently using the second one, and it seems to work okay, but would I gain anything by switching it to "Auto"? And can someone give me an idea of which areas in the world I could get decent 2G or 3G reception with that selection of settings available?

No one...?

WCDMA / GSM auto problem

Hello Guys,
I'm experiencing a problem with my Froyo Desire for probably a week now.
The thing is that in certain areas my Phone can not receive calls / sms or such. In other words "GSM services" dont work. 3g though works fine (stable, strong and fast connection) My Provider is T-Mobile.
After quite a lot of testing I was able to isolate the error:
When WCDMA / GSM is chosen by the phone automatically it seems to me as if it didnt switch "back" to register with my provider via GSM when i want to make a call or if someone wants to call me.
When i switch to "GSM only" manually everything works fine but i have no 3g of course.
I also experience this problem only in certain areas. I live in an area where there is really strong HSDPA available (up to 7mbit\s). When i go to other places of my city i still get HSDPA (not as strong) but calls / sms still work.
The last paragraph may be of no importance, i don know.. probably it helps..
I have googled quite much about this problem and also found a few persons experiencing the same issue but nobody was able to come up with a solution.
I would be very thankful if someone could try to figure this out.

gsm only Desire?
I'm having a nightmare with 3g 2g connectivity on my Desire on the three network whilst at home. If I could manually select gsm only this would be fine as I could still call and text and use wi-fi. Unfortunately my options are gsm/wcdpa (or whatever) auto or the 3g only.
can someone please advise if it is possible to select gsm only and if so, how?
many thanks

Can someone please advise me how if possible, to set the desire to gsm only?

Wireless and network-Mobile network- should be here somewhere.

Thanks, but there is no option for gsm only. It's wcdma only or gsm/wcdma auto. there has to be a way around this.

Similar problem, different version
I've experienced similar problem.
In some area, I can get steady grps signal when I switched GSM only on; but when I switched WCDMA/GSM on, I could get no data connection at all.
I'm using China Unicom's mobile service.

Solution
Hi there,
I've the same issue and I fix it allowing the option GSM/WCDMA Auto in the configuration menu.
Then enter the following code *#*#4636#*#*, select "phone Information" and set preferred network type, set "GSM car (PRL)".
Sorry about my bad english.

Desire low to no signal at home

Hi guys/gals,
HTC Desire A8183 nextG Telstra bought outright.
All works fine with as supplied 2.2
The biggest headache is phone signal strength ... at home usually ...
0 bar = 109-113dBm / 0-2asu
1 bar = 107dBM / 3asu
3 bar = 97dBM / 8asu
At work ...
4 bars = 51-61dBM / 23-31asu
This is with Telstra nextG sim in, at the moment I'm using Amaysim (Optus) and it's the same maybe a little worse.
Sometimes when you first activate the screen there's no bars then 4 then 3-2-1-0 again, with Amaysim you get broken conversation and occasional resend txt messages and telstra most times conversation was ok and no resend txt's.
I'v seen you can change radio ?! to help with signal strength ... or would it be better to root the phone and use ???? program, as mentioned it all work as I need except signal so not looking for better battery or features just get a better signal.
Side note are the program's used to root the phone only run on Windoze ?
I use Intel iMac
Thks Greg

To change the radio, you must be ROOTED.
Unrevoked works on Mac, as well. Download it from here.
BTW, are you getting a good signal at home with other phones with the same SIM Card?
You may also try set this:
Some users experience longer battery life, if they switch from WCDMA preferred to GSM auto (PRL) - mostly in areas of bad reception.
To do this enter the Secret menu on the phone (*#*#4636#*#*), hit Phone information and set it under "Set preffered network type".

Thks nagypapi,
Yeah LG U990 same problem on 3, Telstra nextG and Amaysim sim's.
WCDMA only, GSM only, GSM/WCDMA auto ... there the only choices in "preferred network mode" this is available in menu on 2.2 with going into the secret vault.
GSM only shows better signal bars but is worse in a call, I leave it on GSM/WCDMA auto.
I see there is more option in the vault might try them.
Is there any program that you would suggest that's ezy without to many problems as mentioned all the function in 2.2 are fine for me just need to get better signal.
Thks Greg

What is your current Radio (Baseband version number)?

Baseband version # 32.48.00.32U_5.11.05.14
Greg

Okay, so there is newer version, which I am using. The good news is, that the new radio is more battery efficient. The bad news - reception remained the same.
Bottom line, installing it won't get rid of your problem.
You need an antenna to boost your signal at home - because you've said, that you have problems with all of your phones.
Found some sites, take a look around:
http://cellphoneboosterstore.com/
http://www.alternativewireless.com/cellular-antennas/improving-cell-phone-reception/antennaadvice.html

Thks again nagypapi for all you help and the links ...
I'v emailed telstra's customer service to ask if they would refund my money on the phone it's there own nextg branded phone on there network doesn't work,
there coverage map shows I should get full service, not holding my breath but feel like a bit of sh!t stirring is in order.
Greg

I hate to burst your bubble, but for starters, I doubt your phone is defective. Secondly, a coverage map means nothing. If you're in a valley for example and the towers are on the other side of the hills, you're gonna get bad reception.
I agree in some ways that a newer radio might help things. But ultimately your phone can only receive a decent signal strength if the coverage in that area is of that strength.
Perhaps go with one of those signal boosters.

Nexus loses Vodafone UK connection...

All
I took delivery of my new SIM free Galaxy Nexus today. Everything appeared to be going well until I tried to make a couple of calls. The call would either connect for three seconds and then drop or drop immediately. After dropping the call the handset indicates that it has no connection to a network.It will also drop any incoming calls and then I lose the connection to Vodafone.
To reconnect to Vodafone I either have to turn airplane mode on then off again or reboot the phone.
When it has the VF connection in the connection status page I see this;
Network - Vodafone Uk
Signal Strength - -95 dBm 9 asu
Mobile Network Type - HSDPA:9
Mobile Network State -Connected
After attempting to make or receive a call;
Network - Unknown
Signal Strength - -113 dBM 0 asu
Mobile Network Type - Unknown:0
Mobile Network State - Disconnected
I called Vodafone and they are sending me a new SIM (I've had this one for many years now). The current old SIM works fine in my old Desire.
Anyone else have these issues or have any advice? Is this a handset issue, SIM or could it be a problem with the VF network?

Ah someone else with this issue! I thought it was just me. I find that the vodafone connection drops and won't reconnect - particularly when I'm driving along. Sometimes it's fine for hours and others it just never returns.
I'd be very be very interested to here if a new SIM fixes the issue, as I too have had this sim for a very long time.
I love the device, but if it doesn't function as a phone I'm seriously considering either changing networks or returning the phone (which I got from phones4u).
My old sim works fine in my nexus S (which my wife has taken over and probably won't give back!)
I am still waiting for the volume bug fix which appears to have a new GSM binary, that may help the issue (or not) - otherwise its a call to phones4u to get me moved networks!

I got the volume fix when I powered up the phone today but that hasn't sorted it. Im off to a mates house now to try his SIM otherwise I may have to send the phone back.
I've posted this up on the Vodafone forum too -> http://forum.vodafone.co.uk/t5/Goog...-Signal-3-seconds-into-call/m-p/943023#M12291

Just to update - tried with a mates Vodafone UK sim and it worked fine so its looking like my old school SIM needs to be updated...

Just been to a vodafone shop and got a new sim. Made three consecutive calls. A record. New sim seems to fix it!
Sent from my Galaxy Nexus using XDA App

I'm on T-Mobile in the US and seem to have this same problem. I had my G2 and G1 with this SIM and never had an issue, but brought it to the Galaxy Nexus and randomly I lose connection and it won't reconnect until I reboot.
Anyone else see this issue?

I had a similar issue with an O2 sim on an SGS2. Replacing the SIM worked for me, though it was only 2 years old. I suppose its inevitable SIMs will fail.

Unfortunately, I got a new SIM card last night and put it in. But it just happened again today. Anyone have any ideas?
Currently I'm using Android Revolution 1.3.1 and Kernel 3.0.1-ga052f63.
