Roaming T-mobile

[solwaymeg]

T-mobile....very slow!! Has anyone experience of using ipad on T-mobile? Do you have the same problem?
I bought my ipad to use on our yacht in UK/Irish Sea area. I am very disappointed to find that the 3G connection is so slow. It will cost me a small fortune to use via T-mobile!
I can see me only using my ipad when I can access Wi-Fi.
