Softbank Corp. said Monday it has lodged a complaint with the telecommunications ministry over its plan to allot a new radio bandwidth exclusively to mobile phone giants NTT DoCoMo Inc. and KDDI Corp.
Softbank Chief Executive Masayoshi Son told a news conference in Tokyo the bandwidth should also be given to his Internet-business investing firm, which is ready to enter the wireless communications market as soon as regulators give the green light.
A week ago, the firm said it will launch a discount land-line phone service in December.
