Call landlines in most countries from 4p per minute (see website for details) and text worldwide for just 10p. For example call France, Germany or Poland (Landlines) for 4p per minute. You can buy a sim pack from Phones4U for £9.95 - or you could do what I did and buy a simcard direct from lebara-mobile.co.uk - for only £2.99 and this includes £1.00 of credit !! This is a pay-as-you go service for your mobile and it is possible to buy credit online or at more than 50,000 shops including the Post Office. I believe that they use the Vodaphone network so coverage is good. It is also possible to port your number over to Lebara if you want to. This may not be of use to everyone, but it certainly helps me know that Orange have increased their charges to France to 38p per minute !! Hope it helps others.
