Internet Tariff Comparison

You can usually find a table of current internet data tarriffs of all networks buried at the back of a buyer's guide brochure from the Carphone Warehouse or maybe even The Link.

The last time I checked about a month ago, I found that Orange seem to be the best value when you buy an 'extra', if you are on pay as you go.

For 4MB in a month for £4, text 'WORLD 4' to 6610.
For unlimited access in a day for £1, text 'WORLD 1' to 6610.

Special offer in June for World Cup:
For 15MB, text alerts, and wallpaper etc. during 40 days for £6, text 'WORLD CUP' to 247.

Not sure who is the best value if you are on a contract, but overall I guess it all depends how much you will use whether you are on a contract or not.
