T-Mobile announces substantial price reductions for international roaming rates
T-Mobile had already cut roaming prices for its customers several times in the past and announced on June 1, 2006 its greatest ever reduction in wholesale prices for roaming services. It agreed with a number of European network operators to reduce the maximum charge to 45 cents/minute starting in October 2006, and to 36 cents/minute starting in October 2007. This represents roughly half the current average wholesale prices. The network operators have pledged to pass the resulting cost advantages on to the customer quickly and to the greatest extent possible.
