Softbank Mobile Corp. President Masayoshi Son apologized Monday for the system crash this weekend that forced the company to stop taking subscription and cancellation applications for its phone services.

"I apologize for causing troubles not only to our customers but also for bringing about transaction disorder with DoCoMo and au," Son told a hastily arranged news conference at a Tokyo hotel.

Son also said the company will cut its current cell phone service fees when its customers make calls to users of other carriers, starting Nov. 10.
