China's Guangdong Provincial Communications Management Bureau (GPCMB) says that each of the major telecom operators in Guangdong has begun to create ways to ensure users can easily unsubscribe from short message services and also lodge complaints about mobile text spam.

GPCMB's statistics show that of the 400 complaints received last year, a considerable part were related to the unregulated charging of short messages, and of the 226 complaints made on service quality, more than half were about junk unsolicited text messages.

GPCMB says that according to relevant regulations, service providers who have seriously broken the rules will have their business licenses revoked.

Users can report complaints by forwarding the message they received or calling the respective hotlines opened by the telecom companies.
