Activesync mail not working over cellular connections (T-Mobile UK)

I have a touch pro 2 running a 6.5 ROM and I am having issues getting activesync (Exchange) mail working over cellular connections.
I have set it up, all seems OK. I can surf web pages, though it is slow - HSDPA does not seem to come up much. I am in London on T-Mobile with a flat rate data plan (Web-n-walk).
Activesync mail does not sync over cellular. If I manually initiate a send/receive, it often does nothing, sometimes pops up a notification to say that connecting to the internet access point (general.t-mobile.co.uk) failed.
If I enable wifi (just regular wifi, not wifi activesync) and connect to my DSL connection, it all works fine - so I am 99% sure it is an cellular issue or an issue with my phone provider.
Can anyone give me any advice, T-Mobile customer support is getting me nowhere.

Can I set WM TP2 to only retrieve emails using wifi?

Just got back from France, I have been connecting to wifi over there, but emails still seem to be retrieving using 3g which has cost me £10 for a few minutes! if I turn off data connection it seems to turn itself back on, is there anyway to only retrieve by wifi, in the end I was using my daughters ipod touch for email (have to say what a delight to use - simple to set up, smooth, and held onto a wifi signal really well)

Use the app No Data. It will turn off your data connection and the phone will only be allowed to connect by wifi or not at all.

Thanks Denco, I have installed it, but cannot understand how it works, nodata shows "mobile web & o2 active" I have disabled these, can I now exit the application? I have turned off Wifi, but I can still send emails/browse, is this correct? will it block all 3g traffic or just when I am roaming, allowing me to use my 02 network when available?

Can I turn off data plan access on AT&T Smart Phone?

So I've had this HTC S743 for about 5 days and I thought I had it setup correctly to use wifi for data comm.
wifi enabled and selected to use my home network. I can see the radio tower status icon and my locally named network is also displayed.
Under the comm manager the data connection is off.
I have a very simple $45/mo plan with no monthly data plan.
Over the last 5 days I have been surfing the web a bit did some email tests with my ISP and used the on board GPS app which is horrible. Not heavy usage but experimentation to see if I like how the phone works.
After 2 days I get an email from AT&T that I have extremely high data usage exceeding my account limit (for having no monthly plan) and that I should sign up for a data plan at once.
$29 over 2 days for this little bit of fluff? A total of 2,900kb in data.
So I call up AT&T and they tell me this and that and want me to sign up for a plan which I may do. But I want to be able to know that the datacomm is happening via WIFI when I can see a selected WIFI is in service.
They also told me that all GPS data is forced through 3G and bypasses WIFI???
Can anyone here give me an idea about what I may be doing wrong and whether AT&T is correct about the GPS service?
Is there a better GPS app that doesn't do this? This one pretty much stinks anyway. A resolution of 1000 meters doesn't cut it.
AT&T also informed me that I can't have a smart phone without a data contract. Really? I've had one for 6 years like that but it wasn't WIFI capabale and too small to bother with web access.
Thanks for any light you shed on the subject.
One thing I have subsequently found out is that if data connection is off and WIFI is off then when I go into IE and start surfing it does bring up pages. Then when I go back to the Comm Manager the Data Connection to check the status of my connections it is still off for an instant and then it automatically turns itself on as though it had been turned on by use of IE and the status was just being updated.
Last night I installed a newer version of Google maps and was only able to install it via the web browser as opposed to via the Activesynch application on my PC. I was concerned that this might trigger turning on the 3G connection. So I had it set up for a WIFI connection ONLY and installed the app. Afterwards I went into the connection manager and once again the data conn. was turned back on so it's possible that it utilized AT&T's 3G network instead.
Is there any way to control or stop this?

GPS data doesn't have anything to do with 3G/Wifi data......

I know it's supposed to be positioning via the satellites through the GPS antenna but the the description data is coming over the network right? So it appears that even though I'm setup for WIFI access and it's showing as connected with an IP address etc. when I try the Googlemaps GPS app it turns the data conn. for 3G back on.
Thanks for chiming in ...
I have been copying over and installing some new apps to try out this morning via usb. WIFI is on and I'm loged in. None are datacomm oriented that I know of (unless they'r trying to make an internet access to notify about being installed) none the less I just checked again and my data conn. is once again turned back on. Is this typical behavior for a windows mobile phone (6.1) or is this just an AT&T "feature".

Sorry, I don't have a WM6 phone!

Phones switches to 2g during call - (3G) data is disabled

Hi everyone, I'm running Android 2.3.4 (OpenSoju Rom) on my Nexus S,
but the issue i'm going to describe has happened to me on other Roms and
even on my old Nexus One.
When the phone is idle, 3G data works great (also when using apps that
require an internet connection), but when I receive a call,
after a minute or two, the 3G icon disappears from the notification
bar and the phone data connectivity is lost - no connection to the internet.
I've asked around and someone told me it is because the phone switches to
2G network during the call and when in the phone is in 2G mode, during a call
there is no data (on a 2G network).
I know that in the past this behavior did not occur, and in my country
when in 3G during a call - data is enabled!
So does anyone know how to fix/change the setting that causes this behavior?
'cause, for me, sometimes I really need the data connection during a call,
for example, when navigating using Waze (which needs data connectivity),
and receiving a call it causes Waze to stop working and I lose my GPS direction.
Thanks.

Use to work for me too. Then i noticed when AT&T started saying the had talk and web at same time, mysteriously it started doing what is happening to you. And i have Sprint, unless you switch to at&t you might be waiting for awhile.

Is there a way to alter WP7 Data Connection Preferences?

I have a WP7 phone and I have access to wifi except while I'm on the road. The phone automatically connects to the wifi. I have noticed that the data usage is ALWAYS going through my T-mobile account rather than wifi. How can I make sure that the phone uses wifi whenever available, and T-mobile when there's no wifi connection?

It DOES switches to WiFi when available and automatically switches to data Connection when WiFi isn't available. I confirmed it few days ago by installing Counters app for my Lumia 710. It tells you your mobile data usage. It stopped when I connected to my home WiFi and Data Connection was still ON.

Maybe the Lumia is better built than my Samsung Focus. I swear the Focus cannot automatically do this. Maybe it's because it was made for AT&T and not T-mobile.
