How to Link NIN to 9mobile 

The Nigerian government has made it compulsory that all citizens must link their national identity number (NIN) to their networks.

The federal government has mandated the Nigeria communications commission (NCC) to ensure that all active sims are registered and linked to a national identity number. Failure to do so leads to the deactivation of the sim card.

Because of the traffic caused by the critical linkage of NIN to sim cards, various outlets have been set up all across Nigeria for easy access to registration and linkage.
