I had an eighteen month contract. Twelve cheap months followed by six expensive ones. The idea was I could renew after the first year and stay on the low rate. I'd already decided to quit so accepted the six expensive months and then they tried to stick me with a seventh. I'm still not entirely sure I've escaped the extra month. I think I have but only time will tell.

I've got a Vodafone data dongle on pay as you go and it will be way less than half the price of expensive Talk Talk and also cheaper than their cheap price. I've got a separate mobile phone for calls but I hardly ever use that anyway.

It's land line rental that is the big cost. I'm guessing that that's where all these companies rake in the money. I've been tracking my data usage for the last three weeks so I'm pretty sure of what I will use in future. I expect to save between two and three hundred pounds a year.
