This only happens when I stay with a friend who has given up her computer. It happens maybe once or twice a year and for that time I would like to be able to use the iPad.
I've asked a couple of telephone shops, but they say it is not possible to have it as a PayAsYouGo feature, you just have to buy (something) and use it or lose it, be that a day, a week, a month or a year.
Trouble is that I don't understand the jargon and don't want to spend money on something I don't use.
Any thoughts?
