The Nigerian Communications Commission (NCC) has said that the long-running SIM registration campaign will be brought to an end on 30 June 2013, after which all unregistered lines will be disconnected. Local newspaper This Day cites the NCC’s director of Public Affairs, Tony Ojobo, as saying that the decision to end the registration exercise, which began on 28 March 2011, was taken after a meeting between the regulator and the country’s service providers. ‘There’s now a window opportunity for those who have not registered their SIM cards to do so, otherwise from 30 June, they will be [unable to] use the number anymore to make calls,’ Ojobo said. Subscribers were initially given six months (until 28 September 2011) to register their SIMs or face the disconnection of their service, notes TeleGeography’s GlobalComms Database. At that date, the NCC said it had begun the harmonisation of registered SIM cards, which involves the collation, reconciliation, cleaning and consolidation of the captured data into a central data infrastructure. It also revealed that it had extended the registration deadline for a ‘limited period’ to allow any remaining subscribers to register their details. ‘This limited period provides the last chance for all users of existing SIM cards to register, as all unregistered SIM cards will be disconnected without further notice at the conclusion of the harmonisation period,’ the NCC said.
