On 15th December 2020, the Nigerian Communications Commission (also known as NCC) issued a directive titled the "Implementation of New SIM Registration Rules" to all mobile network operators in Nigeria.

The initiative instructed mobile network operators to deactivate all SIM cards which had not been linked with a valid national identity card in 14 days with effect from December 16, 2020. The deadline has since been changed to 9th February 2021.

Although many Nigerians still aren't happy with the short amount of time allocated for this exercise, one thing is for sure: you need to link your NIN to your SIM card before the deadline, or your SIM card will be blocked. Don't know how to go about this? Here's a helpful guide on how to link your NIN number to your SIM card easily.

And that's it! As you can see, the process is quite simple if you already have your NIN. However, the procedure becomes complicated if you have never registered for NIN before.

When is the deadline for NIN SIM registration?

Initially, the deadline was 30th December 2020. Later, it was extended to January 19th, 2021 and further to 9th February 2021.

Despite pleas by Nigerians to have the deadline extended (citing problems with outdated facilities of the NIMC and the COVID-19 restrictions), the federal government has insisted that the February 9th deadline will not be changed.

Furthermore, the Nigerian Communications Commission has revealed that mobile network operators have been instructed to shut down SIMs not linked with NIN after the last day or have their licenses revoked.

What is mandatory SIM registration, and why is it necessary?

Mandatory SIM registration is an internationally-recognized policy that requires users to provide personal information such as their names, addresses, national identity numbers etc. to register for or activate a prepaid SIM card. If a country adopts the policy, users who fail to register their SIM cards face network disconnection.

Mandatory SIM registration, coupled with the NIMC Verification Service, will be helpful in the tackling of crimes and in the identification and subsequent arrest of criminals and fraudsters (especially those who use their phones for their undertakings)

As you can see, the entire NIN-SIM registration process is not complicated at all, as long as you already have your National Identification Number. The procedure only becomes complicated for those people who had never obtained their National Identification Number before. All in all, make sure that you link your National Identity Number to your SIM card before 9th February, 2021 to avoid getting your SIM blocked.
