By Emma Okonji and Ugo Aliogo By The federal government yesterday extended the initial deadline fixed for the integration of Subscriber Information Module (SIM) cards with National Identity Number (NIN), from December 30 to February 19 for all subscribers without NIN and from December 30 to January 19 for all subscribers that have already obtained their NIN. It also suspended all USSD and verification charges for the duration of the extension. The federal government, last week, had ordered the Nigerian Communications Commission (NCC) to enforce the SIM-NIN integration within two weeks period from December 16 to 30, with a further order to enforce the blocking of the SIM cards of any subscriber that could not complete the exercise with two weeks.
