How many coins nave you got in your pocket right now? Three? Two? A bent one?

  With a phonecard you can make up to 200 calls without any change at all.

  Go to a telephone box marked(you guessed it)“phonecard”.Put in your card, make your call and when you’ve finished, a screen tells you how much is left on your card.

  (2) Now appear in a shop near you.

  Near each Cardphone place you’ll find a shop where you can buy one. They’re at bus, train and city tube stations(地铁).

  Many universities, hospitals and clubs. Restaurants and gas stations on the highway and shopping centres. At airports and seaports.

  (3) No more broken payphones.
