The Nigerian Communications Commission (NCC) has extended the deadline for the country’s mobile subscribers to register their details, The Nation reports, citing a statement signed by Reuben Muoka, the regulator’s head of media and publicity. Muoka said that the NCC has begun the harmonisation of Nigeria’s registered SIM cards, which involves the collation, reconciliation, cleaning and consolidation of the captured data into a central data infrastructure. ‘Given the vast geographical spread of the country, and the logistics involved in the registration exercise over the past six months, there is need for proper harmonisation of the data in line with the specifications issued by the commission,’ he said. The six-month SIM registration exercise was scheduled to conclude on 28 September 2011, but the deadline has now been extended for an unspecified period during the harmonisation process 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.
