As I am in and out of Blighty about once or twice a month now, it is not worth my while to get a post paid connection but I'd like to stay connected while on the go. I already have a MyFi dongle thingy from three.co.uk that I use with my home provider outside the UK. What I need is a sim card and a cheap and cheerful connection to run my yuppie gadgets (either iPhone and iPad or netbook) off it without the roaming costs getting out of hand, any experience, recommendation what is best? Again, has to be prepaid / pay as you go though! Cheers.
