SHANGHAI telecom authorities are urging mobile phone users to register their identities at service providers as soon as possible — or risk being cut off.

The country's industry watchdog recently announced that all phones must be registered by June 30, 2017.

Local telecom companies will phone or send text messages to users who have not registered using their real names or whose registered information is incomplete or incorrect, urging them to finish the process by the deadline, said Shanghai Communications Administration.
