T-Mobile has cut by more than half charges for business customers who transmit data over its mobile networks in countries where it operates its own network.
Sending and receiving data over a T-Mobile network would now cost £3 per megabyte of data transmitted instead of £7.50, the firm said in a statement.
Business travellers in Austria, Czech Republic, Croatia, Germany, Hungary, Netherlands, Poland, Slovakia and the UK get the cut, it said.
In the small print, the firm said "Officelink customers, customers using BlackBerry e-mail or Sidekick devices" would not get the price cut.
Max Miller, head of carrier services at T-Mobile, said that the price cuts had been possible because of the volume of data it was handling across its own networks, but refused to say how much that was.
Its own country operations had negotiated the price cuts among one another and it was now talking to other carriers to get reductions for business travellers outside of T-Mobile's footprint.
The firm said in the statement that it planned to make similar reductions for consumers.®
