Well I can HIGHLY recommend the T-Mobile Web n'Walk Professional Datacard.

3G+ Datacard with "unlimited" (2gb fair use) data. In 3G areas I consistently get 390kbps speed which is perfect for most web browsing and not bad at downloading. From Aug they will switch on HSDPA which is essentially 3G on speed and will offer speeds up to 1.8mbps.

And you also get a T-Mobile Wifi Voucher to give 12 Months Hotspot access! That is normally £23.99!

And you get all of this for a grand total of £20/month inc VAT!!!

The card works superbly and when you go to connect it searches for T-Mobile Hotspots (found at the airports) and if no hotspot it connects at 3G or then it flicks down to GPRS.

Apply through www.quidco.com and get £12 cashback on the application and pay £58 for the card if you sign a 12 Month Contract or free if you take the 18m contract.
