I've never used 3, so can't comment on their service. I've heard it said that their coverage isn't the best, but I've heard others say that they've had no problems. Depends on your area, I guess. I'm always a little bit wary of these deals, and have in the back of my mind that "if it looks too good to be true, it usually is", but on the face of it, I can't see that you could go far wrong, and if you have your own phone, you can always move to another provider at the end of the contract if necessary. One thing I did notice at the bottom of the page is "The price displayed includes a £5 monthly discount for paying by a recurring method, such as direct debit. Each May, your Monthly Charge will increase by an amount up to the January RPI rate (published each February)." I don't know if that would apply to this May, but I guess it wouldn't be all that much of an increase anyway. Just watch that the price doesn't shoot up after the end of the one year contract.
