I'm currently lodging with the outlaws so don't have a broadband connection. I was on dial-up but decided to give mobile broadband a go. Went with 3 as it was the best deal and it's made a lot of difference. Started on the 3Gb package (£15 p/m) and upgraded to the 7Gb at £25 p/m. It's not true broadband but it's much better than dial-up. You'll need to check your coverage to make sure you're in a good reception area.
