TOKYO—Just five months ago, SoftBank Group Corp. chief Masayoshi Son said it was “key” for him to keep U.S. mobile carrier Sprint Corp. in his empire and he would “really regret” it in 10 years if he ever lost control. Son appears ready to put that prediction to the test. People familiar with Mr. Son’s thinking say he is ready to enter a deal to combine Sprint with T-Mobile US Inc., a move that would cede at least some control to T-Mobile parent Deutsche Telekom AG.
