SoftBank Challenge to Cable Won’t Avoid T-Mobile Scrutiny

Billionaire Masayoshi Son says his wireless Internet service can challenge U.S. cable companies with lower prices and increased speeds. The pitch probably won’t quiet regulators’ qualms about his plan to buy T-Mobile US Inc.

Son, the president of Japan’s SoftBank Corp., told an audience in Washington yesterday that he wants to invest in high-speed mobile broadband service to compete against companies such as Comcast Corp. and Verizon Communications Inc. that offer fast Web access over wires.
