Companies like Sprint and French wireless provider Iliad tried to purchase T-Mobile in recent months, but their bids were turned down. Now its owner, Deutsche Telekom, which has a 67% stake in T-Mobile, says other companies may be interested in buying the mobile provider, including Comcast, America Movil and Dish Network. Deutsche Telekom's CEO Timotheus Hoettges also said at a Barcelona conference that Masayoshi Son, a Japanese billionaire who operates Sprint via SoftBank Corp, may also look for ways to gain share in the U.S. market. Though Hoettges says a sale is not imminent. Shares of T-Mobile ended the trading day up 1.7% at $27.92 per share. The stock is down 17% since the start of the year.
