A national campaign to identify mobile subscribers will begin in Cameroon on December 21, the Telecommunications Control Agency (ART) told APA on Friday.

Having noticed that the use of mobile phone has become a recipe for scam, usurpation, threats or terrorist acts, ART has called on operators to update their databases.

Unidentified numbers will be systematically deactivated.

A similar operation was conducted in August 2014 to find that several mobile users were unidentified, falsely identified or identified with a false identity.

Other deficiencies witnessed between May and June 2015, showed that some owned dozens of SIM cards linked to a single operator.
