TOKYO (AP) — Some users of SoftBank cellphones had problems calling and text messaging for several hours in Japan on Thursday ahead of the company’s IPO which is set to be among the world’s biggest at about $21 billion.
The mobile service’s problems started in the early afternoon and were gradually being fixed, according to SoftBank Corp. spokesman Naomasa Suzuki.
He said they were caused by a mechanical problem in Softbank’s 4G telecommunications systems. In some cases, the 3G network services automatically kicked in.
SoftBank is a top cell-service provider in Japan, with some 40 million users.
Son, who has denounced the killing, has been partnering with Saudi Arabian Crown Prince Mohammed bin Salman and about half of his $100 billion Vision Fund, established in 2016, comes from the kingdom. The fund has been investing in various companies, solar projects and artificial intelligence.
