T-Mobile Austria has cancelled a planned press conference, throwing doubt on its much-rumoured takeover of rival cellular operator tele.ring. It had been expected that the German-owned cellco would announce its acquisition of tele.ring from Alltel Corp for around EUR1.3 billion. Combining with its rival would take T-Mobile Austria’s customer base from around two million currently to three million, putting pressure on the market leader Mobilkom which has 3.3 million subscribers. The company gave no reason for the cancellation of the press conference. The board of T-Mobile’s owner Deutsche Telekom has approved the purchase.
