MDA Pocket PC help.

[TEAK36]

Hi,
I have purchased an MDA Vario PDA, and I am completety stumped with regards to connecting to the internet.I have followed the instructions in the Manual to set up WAP and GPRS, but something is still not right.When I try and connect to the internet, the MDA GPRS box comes up and asks me if I want to connect, and when I click ok it even shows me that I am connecting to Vodafone WAP and that my type of connection is GPRS, but then a box appears saying that the page cannot be displayed because the connection is lost.The MDA still shows the connected icon, and I have to click on disconnect to shut it down.The same happens with my email, but I know the details I input are correct because I can connect wirelessly at home and pick up my emails.I am on the verge of chucking the thing out of the window.
Any advice would be most appreciated.
