They are available in my area, but checking withe friends who have TT I decided not to touch them, if it works then great, if it doesn't then you have had it you can be without a phone not only broadband for weeks. e.g. my BT phone line failed just before Christmas last year, I reported the fault at 09:00 an engineer was around at 15:00 to fix it, allegedly a wire had rusted at the main junction box on the road. That is quality the service I want. OK BT like all companies do have their issues but on the whole they are OK, in my experience.
"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for - in order to get to the job you need to pay for the clothes and the car, and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman
