Travelling abroad? Try http://www.holidayphone.co.uk

Using UK mobiles in Europe is now just about affordable thanks to an EU regulation that has forced the European operators to have sensible call rates (at last).

BUT travelling further afield is still a lottery and the charges to make and receive calls, and especially use the Internet when abroad, are horrible, truly horrible.

For our trip to South Africa I'm trying http://www.holidayphone.co.uk and so far it has gone really smoothly.  Their service not only supplies you a PAYG SIM for the country you are travelling in, but also a means by which calls to your normal UK number get forwarded to your mobile when abroad without incurring the usual charges.  Clever stuff!
