Softbank Corp’s mobile arm added more users than its rivals in August, the 16th consecutive month it has achieved the feat. Softbank Mobile signed up a net new 163,300 customers last month, down from 215,400 net additions in July – the month in which it launched the much-hyped iPhone. Data published by the Japanese Telecommunications Carriers Association (TCA) showed that Softbank Mobile ended August with a total of 19.490 million, ahead of market leader NTT DoCoMo which added a net 84,400 users to raise its total to close to 53.807 million. Second placed KDDI gained 54,900 subscribers on a net basis to end August with 30.376 million subscribers, while number four operator eMobile added 84,300 for a total of 752,400. The country’s largest PHS operator Willcom lost a net 17,400 users to end August with 4.599 million, compared with 4.772 million at the start of the year.
