In response to calls for a crackdown by the People's Congress of Shenzhen, the Shenzhen Municipal Technology and Information Bureau (SMTIB) says relevant rules will soon be promulgated to deal with the nuisance of mobile text message spam.

SMTIB says that rules are being made to manage short messages. The rules will define responsibilities and obligations of telecom operators and application service providers and will specify punishments if the rules are broken.

SMTIB also says that the technology for filtering short message spam and junk was being improved to allow only pre-subscribed short messages to come into Chinese users' mobile phones.
