Ministry, mobile phone services firms to jointly cope with spam.
The telecom ministry and six mobile phone services providers formed a liaison group Thursday to jointly cope with spam.
The Public Management, Home Affairs, Posts and Telecommunications Ministry and the companies, including personal handy-phone system (PHS) services providers, said they will meet once every month or every two months to exchange information and study countermeasures against unsolicited e-mail messages.
The six companies are NTT DoCoMo Inc., KDDI Corp., Vodafone K.K., TU-KA Cellular Tokyo Inc., DDI Pocket Inc. and Yozan Inc.
While earlier measures taken by the companies to crack down on spam originating with personal computers proved effective, the number of spam messages sent out from mobile phones is rising sharply.
According to the ministry, the number of complaints about spam received by mobile phone and PHS services providers soared to 211,000 during the April-June period from 74,000 in the January-March term.
