Vodafone Japan said today they would limit SMS transmissions starting 31 May 2005 as part of new anti-spam measures aimed at making its Vodafone live! mobile Internet service more dependable for customers. Specifically, the number of SMS that can be sent to from a Vodafone KK 3G handset within one day will be limited to 500 starting 31 May 2005. Handsets that exceed this limit will not be able to send additional SMS for the following 20 days.
In December 2003, Vodafone introduced a new function in its 2G network to limit the number of Long Mails and Super Mails that a handset could send.
The move is part of Vodafone’s ongoing campaign to limit spam mail sent from mobile terminals. The company introduced similar limitations on 3G VGS Mail in March 2004, 2G Sky Mail in November 2004, and 3G MMS in February 2005.
The measures announced today are applicable to SMS on Vodafone KK’s 3G network. With this restriction in place, Vodafone has now introduced sending limitations to all of its Vodafone live! mail services.
