3G connection drops when making/receiving a call

I use a Vario II and even if I have full 3G reception, it reverts back to GPRS when in a call which means I can't browse the web while in a call. It then connects back to 3G asap when the call is over. During video calls, 3G works fine and stays connected as it should.
I know it's possible to have both because I have actually made a test call while on 3G and was browsing the web for a few brief moments at the same time before it reverted back to crappy GPRS again.
Is this T-Mob UK taking the piss like they do with they're bloody proxy which compresses all images or is there something I can do here to remedy it.
Thanks.

Thoughts anyone?

My phone does that in my house (memphis, USA) and the problem i have is not being able to hang up. I found a program called showumts that i believe i got from here. All it does it change the registry so that a band tab is available in the phone options. I can manually set GSM or WCDMA and make it stick. This is not exactly like your problem but maybe it could force WCDMA instead of the Auto option built into the phone. (I have 8525 Hermes)

I have upgrade my ROM to the WWE AKU 3.3 TEST version on the upgrading site.
The details are listed hereunderwith my user CP.
This new ROM is great and I have it displaying G, U and H for GRPS, 3G and HSDPA respectivly.
I am sure that an official version will be released in South Africa soon.
In fact I have also changed the U to display 3G.
So far the ROM is very stable, the bluetooth stack greatly improved, and I have no gripes with the Radio ROM 1.35.

Data constipation? Irregular data movements? Constant disconnects?

Symptoms
- You cannot maintain a constant data connection. The connection is often lost or dropped.
- HD2 reception indicator dances between G to 3G to H despite showing good reception, and user remaining stationary.
Counter measures - No cabs or registry tweaks needed.
Presented in the order I would try them. If the lower number levels don't work, then move up a level. These are offerred as advice from a UK based HD2 user, though may work for you elsewhere.
LEVEL 1
- Go to Comm Manager > Wireless Controls
- Turn the Data connection Off then On again.
This will usually get you back and running again faster than waiting for the HD2 to sort itself out.
LEVEL 2
- Go to Settings > All Settings > Connections > Advanced Network
- Disable HSDPA/HSUPA
This will stop your phone attempting to use '3.5G' and will mean that you only use 3G.
Remember to re-enable HSDPA/HSUPA when you are in an area with better reception.
LEVEL 3
- Go to Settings > Wireless Controls > Phone - Change phone settings
- Move down to Other Options > Band - Change baseband
- Change Network Type from Auto to GSM
- Change Band frequency from Auto to either GSM (900+1800)+UMTS or GSM (1900+850) . To make the decision, you need to know the GSM frequency your operator uses. If you don't know, you can just try both of the GSM options and see which works. No damage will be done by using the wrong frequency first time, and you can change back.
This will disable 3G and force your phone to use 2G. Most operators have decent 2G networks, so you shouldn't have the disconnects anymore, but you will have slower than 3G potential speeds.
Remember to change your phone back to Auto for both Network Type and Band Frequency when you are in an area with better reception.

Thanks for the heads up... will have to try some of these. I find it most annoying at times...!

Thanks for the advice, I do find those issues annoying. What are the benefits of using 3.5G? If they're aren't any major advantages and turning this off helps then I may as well leave it off.

The problem with this is that it b*llockses up your push email settings, if you use the phone to get email from an Exchange server. The better approach (assuming standard configuration) is to press and hold the power/end-call hard-button. That brings up a menu of four choices. The last of those is "terminate data connection". Click it. Anything the phone does which requires the data connection after that will automatically reactivate it.

3G 2100
These tricks may solve the issue for many but not for me because I'm in a 3G 2100 only network so I cannot switch to GSM. I will try to disable HSDPA/HSUPA to see if that works though.
The weird thing is that the issue occurs almost exclusively when I'm logged on an IM client and the phone stays in sleep mode a few minutes (say 15 min or so). After I wake up the phone the signal seems ok but the data connection is lost (IM, browsing, mail, weather update, etc.). It doesn't happen every time but very often, several times a day.
If I don't log on any instant messenger app the data connection is stable, especially with the new 1.66 ROM (I tried both Duttty's custom and official). In this case I lose data connection very rarely, in fact I din't even remember the last time I did.
Can anybody provide an explanation for this, what is happening with the connection between the IM server and the phone during sleep?

If your network supports it, you should have higher potential data upload and download speeds through using 3.5G (HSDPA/HSUPA).
In reality and every day use, on many networks you probably wouldn't notice the difference between 3G and 3.5G.
I'm on Virgin Mobile, which piggybacks on T-Mobile's network here in the UK. My speedtests in central London, show virtually no difference between me using 2G, 3G and 3.5G!!!! Which is ridiculous. The main difference I get as a HD2 user is much more stable data connection on 2G vs 3G/3.5G.

Leo always jumping networks while roaming?

My HD2 seems to act funny when I am abroad/roaming networks. At home on my own network (orange France) its stable and always has very good reception. When I am abroad for work mostly in Germany its constantly jumping networks...You check the phone/quality of network and reception, one minute its on T-mobile with a good reception, then when you pick it up it starts searching for a new network wich takes a long time. One minute its on O2.de then E plus or T-mobile. This all takes place when network selection is on auto or manual! When on manual network selection it still changes networks without any action from my side, this is not normal!! Also its draining my battery alot faster...This way I cannot use my phone when half of the time its searching for a network. I dont have edge or 3G subscribtion, just using the gsm network and wifi network while I am in the hotel...
I am running Artemis 7.0 wwe and have radio version 2.09.51.03_2. Anybody any idea/tips? I would like to avoid doing a hard reset/new flash because the phone is stable and completely setup the way I like it...

3G on and Off

So, i have bugged folks on this forum about getting 3G to work on other carriers, and it turns out - it does work! At first i found out my settings were set to GSM only, but now i also found this weird inconsistency possibly a bug.
If i have Data Off after using 3G or GPRS for some time, when i turn it back on, phone would not connect to data service. After enabling it will simply time out.
I found that if i switch from GSM to WCDMA, and than back, 3G network would connect and work.
I don't know if it's specifically my phone, or a bug, so i'm just throwing it out there.

What carrier are you getting 3G to work? I doubt its working if its anything that doesn't run on tmobiles bands..the icon will come up and stuff but your either getting edge speeds or not getting any connection. I've had this phone show me 3G with full bars and just time out.. I can eveven put in a sim with a sidekick plan or other data plan and it shows 3G but it does not work

Well, i'm overseas and i have used it on Russian carrier Beeline and carriers in two other countries. Now, i do set my connection to WCDMA only, which gives me 3G icon. When i set it to GSM only, i see GPRS icon show up.
So, it does work, i use fring, online radio, google maps. But as far as speed concerned, i have not tested it.
Just ran a speed test using Speedtest.net tool, I get 3951kbps download, and 655 upload
thats 3G

[Q] Unlocked HTC HD2 Data Problem

Hey again everyone, I posted a question earlier about a possible radio issue on a HTC HD2 I unlocked from O2 UK today and I'm now using it on T-Mobile. Basically my problem is that I can access mobile data while my signal is T-Mobile only, but as soon as it switches to T-Mobile/Orange (these two networks now share each others signals), the H (3G icon) turns into an R (stands for Roaming, amirite?) and I get a notification telling me that I've lost connection because I left my home area with roaming not turned on... However, with roaming on I can access the internet constantly, but I'm worried about incurring hefty data roaming charges so I don't think that's a solution.
The phone is running an Android ICS ROM (the NexusHD2 one, thread here: http://forum.xda-developers.com/showthread.php?t=1434860), it was locked to O2 UK and it's now running on T-Mobile/Orange. Also WiFi, GPS and calls/texts work so I doubt it's a radio issue.
Been searching the internet for a while now to find a solution and can't find one, if you can find a thread with the answer please link me
Thanks in advance!

IMO it's not a radio issue!
You should contact your network operator and ask them about this and extracharges for that (strange kind of) roaming...

I once experienced some issues on data roaming while having Wifi turned on. Turning it off made it work fine on my tytungs ICS.
