SOFTBANK MOBILE provides services that block spam mails and misleading invoice mails sent to mobile handsets. The default setting on SoftBank mobile phones is to block mails with specified URLs such as dating sites. Simple settings are also available to allow users to set a variety of spam filtering functions in one easy step. The Simple Settings spam filtering function was further enhanced in November 2010 by substantially raising the limit on the number of mail from specified addresses and domains to receive or reject.

As a measure against spam, SoftBank mobile phones are set to limit the maximum number of mails sent per day from one handset, and as soon as a spam mail transmission is detected on a handset, SOFTBANK MOBILE works quickly to take action against the spammer, including suspending certain services or terminating their contract. SOFTBANK MOBILE provides a spam-reporting center, where customers can report spam by simply forwarding spam mails to the center.
