I have a little problem here: If i turn on HSDPA i get the H icon and REALLY GOOD internet speed, but i can't make video calls. If i turn it off, i get 3G icon, pretty good internet speed and video calls. Can't i have HSDPA turned on AND also have 3G (video calls) ?
HSDPA is used only for downloading data when you hvae it on. Thats a little starnge and sounds more like a bug to me than something wrong with the network or Kaiser

Thanks, i kinda figured it's a bug, although it could be obvious for someone who actually knows how this stuff works that you can't have 3G and HSDPA at the same time.
Can anybody try to make a video call while H icon is displayed, please? (no need to wait for someone to answer, i get "can't make video call" immediately, just dial a bogus number)
I rarely get the H icon, only at the aiport at sertain places. But like austinsnyc said, i would have expected it would switch back automatically
As far as I'm aware, you can't make a video call on any mobile phone while there is a data transfer in progress.
Basically the answer is "yes" because a data transfer session and a video call are mutually exclusive, and the phone only uses HSDPA (and shows an "H") when there's an active session, so you can't make a video call when the "H" is showing...
Just to confuse things further, I'm pretty sure it's the network operator that decides how long their customer's phones hold on to an HSDPA connection...
T-Mobile and Vodafone in the UK are the only HSDPA-enabled networks that I've used, and they both return me to a "normal" 3G connection immediately after a data transfer, so the "H" is only displayed briefly - when the phone is actively transferring data.
After the data is downloaded, the HSDPA connection is closed immediately and my phone switches back to the "3G" icon, which allows me to make a video call. If your network allows the HSDPA session to stay active, then you'd need to end it yourself before making a call...
(BTW, this is just my understanding, please feel free to tell me I'm talking rubbish!)
Thanks guys, your info got me a lot closer to the truth (i now know you can have 3G while HSDPA is enabled in settings).
Those really not interested skip this part:
My problem is that i NEVER see the 3G icon and i can't make video calls if i enable HSDPA, even if i don't make a data connection, just enable it in settings (in my network even the name of the operator changes when i have 3G coverage so i know for sure that if i enable HSDPA i never get anything 3G, no data speed, no video call)
To make things more clear: it's like i have two phones:
1. with HSDPA or GPRS depending on location and availability, this is what i get if i enable HSDPA in settings, no video calls, operator name always "Vodafone RO"
2. with 3G or GPRS depending on location and availability, this is what i get if i disable HSDPA in settings, i can make / receive video calls, operator name "3G Vodafone RO" or "Vodafone RO" when 3G not available
I guess this is operator dependent, and it's probably something with my network, but it's really disturbing since i cant have both video calls AND really high speed data, only one at a time with soft reset. I guess i'll call thier customer service.
Sorry for the big block of text...

Pricipally, a 3G phone could handle a PS (packet switch) connection and a CS (channel switch) connection simultaneously. The Kaiser is, however, apparently not in this class. The unability to set up a video call while there is "H" in the display can be due to the network configuration. If the operator uses the same carrier for both "normal" PS and HS(D)PA you can probably perform a video call while you see the "H". If the network uses separate carriers for CS/PS and HSPA it is quite likely that the operator will not let you make a video call while your terminal is listenig to a HSPA-enabled carrier.

dumb question.... but i was under the impression you could make a phone call and access the internet at the same time. Is this not true?
I was on the phone and tried to access the internet and was told NO. i am on a 3G connection.
Well ofcourse I do not know exactly what happened with you, but some providers have 'buggy' setups that can cause this. Most of those providers are working hard fixing that problem right now.
You can turn 3G off somewhere, I know I've seen it, but now I can't find it. Change the type of connection from UMTS to GPRS/GSM, there's a setting _somewhere_. If you do that, you will only get GPRS connectivity. Try calling and getting data at the same time then, if it works, your provider is not really ready for 3G yet.
Interesting. I am with ATT and 3G seems to be full power in all locations I am using it in.
I cant find where / how to turn 3G off and only use GPRS.
I can tell you that I have tested 3G with internet sharing to my notebook over bluetooth. I was able to talk with a BT headset, and access the internet with the laptop thru the phone, all at the same time. When connected the phone shows "H" or "3G". This is with a Kaiser but I would expect the same from a Tilt. AT&T in Southern Calif. I installed "Schen's 10 button comm manager" and with it's 3G button I can hold off 3G, then the display shows "E" and no simul connections are possible.
You can only use voice and data with HSDPA. GPRS/Edge does not allow this, they use the same band for data as the voice band. If you see the "H" icon they you are picking up the extra data bands needed for this to work. I have tested this will streaming live tv to my phone from my media center via webguide. Even with the "3G" icon i was not able to stream video and talk at the same time, the video would pause while i was on the phone then resume connection when i hung up or the "H" icon appeared.
I can confirm that I'm seeing this bug. There is no 3g towers in my area. I'll be showing the edge icon and be talking and when i try to load a web page, Opera will complain that a data connection does not exist.

It's not a bug... GPRS/Edge is not capable of simultaneous voice/data. You will not be able to do both until 3G is available in your area (though this doesn't explain the OP's issue).
All, I am sure there is a thread on this somewhere, I just can't find it... please help.
I've got an AT&T Tilt with stock ROM, no bloatware. The problem is that when a phone call comes in (or I dial out), it seems to drop or interrupt the data connection even on 3G. Very annoying.
On my 8525 with WM6 ROM, this never happened. I could be connected to the internet (typically connecting my laptop via Internet Sharing on the 8525), and be talking on the phone at the same time -- the data connection was never interrupted. Of course if I was on an EDGE or GPRS network, it would -- but that's to be expected since GPRS/EDGE use the same radio as GSM. On the 8925, as I stated above, a phone call interrupts data even on 3G!
Has anyone seen this? How do I fix it? Thanks.

Yep overhere also... testing all radio roms but all the same... so far no fix found... we have to live with it...
The kaizer is dead... long live the Kaizer...
... to many problems
I'm in Edge country right now, but will be in 3g in a few minutes as I'm getting ready to roll out to LA, I'll email you from the car to test if the 3g and phone call can co-exist.
I think it has to do something with AT&T's cell towers. I also experienced the same issue that when calls came in my data connection would be cancelled. However one day, out of the blue, the 3G icon was suddenly replaced by an H icon. And it is there all the time! Now I can call and download data at the same time.
Thanks... that's bizzare. H means it's using the HSDPA protocol for 3G, U means it's UMTS, I think now the 3G icon shows up instead of U. (I hope I got my acronyms right). But that shouldn't matter! My phone will go between 3G and H, I think based on the capabilities of the towers. There is no telling what will show up in a given spot.
The mystery remains... Come on, all experts out there, share your wisdom. Could this have anything to do with disconnection settings or TCP settings (done via KaiserTweak)?
I think I just found the answer. Went to KaiserTweak, and selected the Data/Disconnect After setting, which I had set to 1 minute. In the description for that setting, It says "warning.." but you can't see the warning unless you go to landscape mode, which is why I never noticed it before. The warning says that with this setting, 3G Simultaneous Voice and Data will no longer work.
Disconect disabled, and a quick test showed that the problem is solved.
Hi all, I'm wanting to know if anyone else seems to be experiencing an issue where during a call the signal icon will change from H to G and the quality of reception / voice also drops to what resembles a non-3G phone.
This seems to happen quite often regardless if the call is inbound or outbound. I can be sitting at my desk and have what appears to be full reception with the H icon, then 2-3 minutes into a call (still sitting at my desk) the icon will change to G and from the quality degradation it must be reducing to 2G... why is this? I could understand if I was walking around but it happens regardless and will never go back up to H during a call only once the call has ended... is this a limitation of the cell network/carrier?
I'm using Dutty's v4, radio 1.09.25.23, Olinex 1.93 hardspl. Network carrier is Optus and I'm located right in the middle of the city - Melbourne, Australia.
I'm wanting to try some of the newer Raphel radios but need to get Security Unlocked first - already PM'd Olipro... just waitin
Any comments ?
Hi,
Same problem to me... downtown of the fifth biggest city in France...
Don't worry if I may say so: the phone is the problem. it has crappy reception, probably the crappiest of all time... I have tried any possible Radio ROM available, none of them changed a signle thing...
Worst HTC phone ever made for reception... All my friends with way cheaper phones have at least four to five bars when they are at my place, I don't get that... but all my other phones do.
Eve worse: the phone totally disconnects from network when I have one or two bars of H or 3G... I receive NO phone call, no SMS and I am notified two days later (30 voice msgs, fifty SMS... all sent two days ago). I even had issues at work becaus eof all this, people complained they couldn't reach me for hours and days...
I now have to set it back to G alone (switch off H or 3G that I want to use all the time...), which is a shame for such an advanced device...
Correct me if I'm wrong, but you're not supposed to get a H during calls, maybe for video calls, I'm not sure. But for regular 3G calls, you shouldn't get a H, H should only appear when there is data transfer, like when using Internet for example.

I'm not really qualified to comment except from my own experience... My phone always has the H symbol, when there is no data activity then the H symble is faded/semi transparent and becomes solid as soon as I make a call or transfer data (eg. updating weather) and I never have the 3G icon - always H or G. I belive this may be related to the operator and the frequencies they use for both HSDxA and 2G modes.
Probably for about 80% of my calls I'll keep the H symbol, but when it drops to G it's really annoying as the quality turns to sh*t
My phone never seems to be able to hold a signal.
I'm on the 3 network in Australia & my phone doesn't stick to the network. If I choose options under the phone and press 'find network' a couple of times it will lock on, but then minutes later I get the 'searching for network'. Over & over again.
My phone is unlocked using the Olinex method, my radio is current & I can't even recieve incoming calls or texts...outgoing is fine (when I've got network0 & I can use browse the internet & use GPS etc...just nothing incoming...
i have a theory on this its called " crap design"! i thinks its because the internal antenna is towards the bottom of the device so when you hold it you are covering the antenna.
try holding the phone with just two fingers trying not to cover the back (below the battery ) this works for me! i only say this out of observation
Could just be the way the network is configured for HSDPA. Voice traffic can be pushed on to 3G (or release 99 as it is sometimes called) to reduce the loading on the HSPDA carrier / layer.
See it as a good thing
Most handsets I have owned usually drop from HSDPA or 3G or GPRS during a voice call, probably just a design feature to save battery life. Should latch back on after call though. I have to say though, I had the MDA compact IV and the reception is positively shocking! dropping signal is soon as I picked it up and i'm in a good signal area! On its way back to T-MO as I speak as this wasn't the only issue. Shame, great form factor as well.
Symbols on your phone are just that symbolic, they don't always mean what you think they mean.
If a UE is on your desk in idle mode and it looks like you have a great signal and a H displayed, great. It means that it is measuring the quality of the network and you have the ABILITY to hold a HS data session should you want. The reception barrs on most 3g UE's aren't a measure of the radio reception but of the amount of noise. More bars less noise, less bars noisey environment.
If you make a voice call, there is no way any decent network would use HS to carry your call as it is wasting resource somebody else could use and of course pay for. Once in a call the UE has to monitor many things and also maintain that call or data session. In simplistic terms if the conditions do not allow the call to be carried over 3G it will step down to 2G. If it was a data session it could go from HSDPA to 3G, then 3G to GPRS.
Also a network could easily by the swap of a 1 or a 0 carry your voice call over 2G without you knowing at all, freeing up that 3G network that cost billions to roll out and pay licence fees for, for data which they can charge more for.

I think they made a mistake in the International English manual where it says the antenna is located at the bottom. Either that or it's different for different regional phones. If you download the HTC Touch Diamond_Asia_English_Manual_Manual_080521.pdf or HTC_Diamond_User_Manual_Asia_WWE.pdf from HTC's site, it shows the antenna being at the top next to the camera.

it's not the phone its the operator fault i have the same prob even with nokia's...if the person on the other part of the line is on gsm the operator will switch u on gsm network...they do this because they don't wont to use often the 3g network

The operators do not do this. Do they switch you to a land line when you call a land line, no. It is all down to radio quality where you are making the call and not what number or type of line you are calling. The phone networks are not that intelligent

Actually, they are, they know what types of numbers you're calling. This is why even for long distance prices, there is a different between calling a land line and a cellphone number. Either way, the system can tell what type of line you're connected to.
Hello all,
Have any of you guys come across this problem with your X1...I was connected to the internet via GPRS earlier this afternoon doing a little browsing and have now received 3 missed call notifications which were made during my browsing.
Does the phone not receive calls when connected to GPRS...very annoying.
I'm using the Touch X 10.1 rom by Smaberg but don't think that is the problem...any ideas!!!
some phone operators with older hardware in their end don't support call and gprs at the same time
not really a phone thing
Thanks for the reply...I'm on the Orange network so I thought they would have been up to speed with technology incorporating call and data at the same time...
Same issue here.
I'm pretty sure that GPRS and voice calls can't work at the same time because of the 2G network, but thought at least the voice call would interrupt the data session.

That's my understanding. 3 & 3.5G allows voice and data at the same time.
but on 2G it's either GPRS or voice... that used to drive me crazy with my Prophet too
Ah, that makes sense...I usually turn off the 3G to extend battery life so that would be the reason I missed calls...may turn it back to 3G if I'm doing a session of browsing in future...
Cheers
even with my 2g himalaya I didn't have any problems with both calling and gprs
it was why gprs was interduced to replace the slower and older gsm dataconnection
which worked the same way as an analog modem which blocked of cause
of cause only class A gprs devices support that
http://en.wikipedia.org/wiki/General_Packet_Radio_Service#Hardware
but all these phones today are that
problem is that class A is required in both the phone and the operators network hardware
Try with RADIO ROM 1.16.
Problem with this rom is apparently solved.
Hi there, hope you can help me.
When I'm home 3g network is not really strong, and my phone keeps switching from 3G to 2G and vice-versa.
This is not a problem itself, but when I'm on a call and the phone switches to 2G the call quality becomes awful: I hear metallic voices, and most of all people can't hear me well.
I decided to use Tasker and the plugin Toggle Network Type to create a "Call" profile which is very simple:
- When in state "Call - Any"
- Enter task -> Set phone network to HSPA only
- Exit task-> Set phone network to HSPA preferred / 2G
What I expexted:
As soon as an incoming call is intercepted, the phone locks network type to 3G. Therefore: if network state is 3G, it stays 3G. If network state is 2G, too bad, it stays 2G because the phone can switch from 3G to 2G during calls but not vice-versa.
What happens;
As soon as an incoming call is intercepted, the phone locks network type to 3G but this doesn't actually affect the call. Even if phone is in 3G when the call starts, it eventually keeps switching to 2G.
This means that the only setting the phone considers is the one that is set at the moment the phone call starts / is received. Whatever I change the next istant doesn't affect that specific call.
Is there a way to remove this obstacle? I'm often forced to:
- tell people "sorry, be right back"
- end phone call
- lock phone to 3G only
- recall them
It's quite frustrating......
The other way is of course keeping the phone locked to 3g only, always... but I'd prefer not to do it.
Hope I managed to explain my problem, sorry for my not-so-great English.
Thank you in advance, cheers
