When I am on a 3G connection, I am not able to talk and send data at the same time. I thought one of the benefits of 3G was to be able to be on the phone and receive data. Is that not the case, or do I need to do something to enable 3G connections to work this way?
Should work out of the box for UMTS/HSDPA. For EVDO you need Rev.A.
Could be your provider has not fully upgraded their hardware yet, there are a few out there that can't handle it (yet). Also, automatic data disconnect tweak found in KaiserTweak and Schaps Advanced Config has as side effect that this disables simultaneous data and voice.

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).
Is there a way to disable GPRS data WITHOUT disabling HSDPA?
(I see the reverse is possible - you can disable HSDPA from [Settings > Connections] and still do GPRS.)
I have three X series and do not want to get roaming data fees. For those uinfamiliar with threes plans, the HSDPA is very cheap but when you frequently and un noticed roam off their network onto GPRS you slugged with large roaming fees.
Ideally I need plain GPRS data always blocked unless I over ride it and at the same time HSDPA always enabled.
Anyone seen a way to do this. I am aware of Modaco "No Data" but it does not fit the bill for what I want.
Yes, indeed there is. Your post prompted me to figure it out. while I don't get hit with roaming or charges for jumping on edge or GPRS, I do really like the 3G service I have and my house is covered. Usually though it's when I'm driving and listening to internet radio or something, It'll jump onto GPRS/EDGE and the buffer will underrun, not great.
So... your question caused me to figure it out.
It's actually in the phone menu however, if you don't have it setup you have to enable this particular tab.
Real Simple Method:
Start -> Settings -> Personal -> Phone
Click the band tab, set network type to WCDMA and leave GSM/UMTS to Auto(don't change this otherwise you'll cripple your phone's ability to tower hop.)
IF you don't have this tab here's how you enable it in the registry.
Either manually edit your registry and navigate to HKLM\Software\OEM\PhoneSetting and change ShowUMTSBandPage to "1"
Or just import my included registry file to enable that tab. Soft-reset for fun and voila. I've done this tweak now and now my phone stays on 3g even when the GPRS signal is far better. I'm quite happy with this setup.
Enjoy
On a stock Tilt, even if that reg key is set to 1, it still does not show the Band tab.
Vexamus. No this it not a solution for me as it changes both Voice AND Data. Making the switch you recommend, kills my voice capability as I am currently roaming. I need to be able to make calls when roaming outside of my home WCDMA network. It is only Data that I want to restrict.
Furthermore having done this, when I set the phone network back to Auto to restore voice, I could not get any sort of connection to re establish. Data or Voice - nada. Even after powering the phone and device on and off!
To fix this I went to the lower GSM/UMTS band box and as I know I am roaming right now, set it to away from Auto to the first GSM option. This allowed the connection to re establish then I set it back to Auto and all is OK again.
So if anyone else sets their network type away from Auto while roaming you may need to toggle your GSM/UMTS band settings to get things back. Once back you can set both to Auto.
ammended Q.
Is there a way to disable GPRS DATA without disabling HSDPA and at the same time without effecting phone/voice roaming?
I am interested in this too

Sorry that didn't work out for you, mate.
I don't have that roaming problem, I have UMTS coverage everywhere I go so no biggie. And I've been flipping the setting back and forth all day and never had any issue with not being able to reconnect. I'll keep researching it.

I don't think that setting the band is possible with an AT&T rom; moreover, I think it also has to do with the radio version.
Do anyone know of a way to change the priority of which network to use.
I want VOICE - default to most reliable [2g] and only use something else if 2g unavailable [networks in UK are notoriously bad at cell tower hand off on 3g connections resulting is dropping calls while driving on motorways]
I want DATA - default to highest speed, fall back to lower speeds as normal.
My options are 3g only, 2g only, 3g preferred - not ideal
I was asking about something like this not long ago. I had idea to automatically turn on 3g when data is on and turn 2g when data is off but at this moment there is no way to do it on stock rom. Maybe when we gonna have working CM someone can add future like this.
Hi
I'm trying to get the best Internet connection on my phone. My carrier doesn't support voice over LTE so if I set the Network mode to LTE only I got no calls incoming or outgoing.
The other options I have are 2G only or 3G only, which makes my LTE data plan useless.
Best option is to have it configured to 2G/3G/LTE, but the problem is that when I'm usually stuck with an excellent 2G connection (with useless internet), instead of a not lousy/not great 3G connection, which still has better Internet speed and stability than 4G.
I'm looking to have my phone only see 3G/4G and not 2G, but I don't have a network mode for that. How can I enable the network mode I require?
I'm rooted so if I can enable it somewhere in the system, that is an option.
Thanks in advance
