T-Mobile has announced a new service in which they will charge British subscribers a flat rate of 55 pence (about $1, or 80 euro cents) per minute to make and receive calls in 29 countries in Europe as well as Canada and the U.S. The service will be available in June.Vodafone is slashing prices even further. Their European customers will pay less than 55 euro cents per minute anywhere in Europe. That compares favorably to the 90 euro cents per minute that the service costs on average now. They will also lower their wholesale rates, promising that resellers won't pay more than 45 euro cents per minute. Those rates will be in place by October.
