adaese and I each have a personal mobile, as neither of us have work ones. Ours are pay as you go. They each cost us about £50 to buy, around four and six years ago respectively. Top-ups cost us, at a guess, around £60 a year in total.

We really only use them when we're out on our own, to ring home and say what time we'll be back; or occasionally to ring a cab etc if we're out.
