£15/month, free USB-stick/dongle, 18 month contract. 1GB/month cap but no extra cost if you go over, they dont seem all that bothered anyway. Been using it for 3 months.

One of the reasons i chose T-Mobile is because of the free unlimited access to the national Wi-Fi "hot spots" which is great whenever i want to use the internet in some cafe or where ever.

On the T-mobile website they got my home street coverage rating as "Very good" (4 of 5 bars), i live in Stourbridge, West Midlands - a very large built up area, and my next door neighbour is the greenbelt - im on the outskirt of town and still got a decent signal from home.

Ive done some tests from time to time from home, using download test sites and downloading different files - some of them each from different server-websites for faster download to get real results.
On average i get:
download: 60-150KB/sec, thats about 1 to 1.5mb
upload: 40-50KB/sec, thats almost 0.5mb
The maximum official ("upto") download limit im supposed to be able to get is 7.2mb.

For online gamers:
Considering ive only as of yet tested from home which is located quite a bit away from a local phone mast...
Ping times are fine, except for FPS type games.
My cable broadband 50mb - Virgin Media landline has very good ping times, and compared to this mobile broadband its about 20-80ms worse than cable/adsl. Checked on WoW, Everquest 2, Battlefield 2.

Sometimes, the connection will lag worse and worse over a couple/few minutes. Ive found by clicking reconnect, then the lag is gone.

Services 8, would give it a 10 if the network wasnt so congested.
Support 10, not had any need for support other than a billing enquiry at the local shop.
Speed 7, very rarely spiking upto 200kb/sec which is 3ish mb? half of the "theoretical maximum" they advertise.
