Japanese carrier SoftBank is reportedly interested in making a bid for T-Mobile as a potential backup plan in case its deal with Sprint falls through. SoftBank’s $20.1 billion bid for Sprint is being challenged by Dish. Reuters is reporting that SoftBank is in talks with Deutsche Telekom AG, the parent company of T-Mobile, about a possible deal to acquire the U.S. wireless provider. The talks between the two companies are said to have “intensified” in the weeks following Dish’s counteroffer for Sprint. Deutsche Telekom owns 74% of T-Mobile USA, which is said to be valued at $15 billion. The report comes shortly before Sprint shareholders are scheduledÂ to approve or reject SoftBank’s offer on June 12th.
