It’s no longer news that the Federal Government of Nigeria recently directed telecommunication companies to bar outgoing calls on all unlinked lines.
Recall that the Nigerian Communications Commission (NCC) had earlier mandated the telecommunications operators in the country to block all SIM cards that are not registered with the National Identity Numbers (NIN) within the stipulated time allotted for registration.
Following this, several subscribers took to social media on Tuesday to express their displeasure over the barring of their communication lines by telecommunication network providers in Nigeria.

However, the Mobile Telephone Network (MTN), in tweets, apologised to the complainants over the restrictions.
Here are what to do to avoid being barred from the network:
How to link your NIN with your MTN line

Enter your NIN and submit or; Dial *785#Your NIN# from the MTN phone number you wish to link.
The number will be linked to your NIN automatically. Visit https://mtnonline.com/nim/ using your phone or computer.

Dial *121# on the Airtel line you wish to link.
Type 1 for “NIN Capture” and send.

How to link your NIN to your Glo and 9mobile lines
For the other networks, you simply visit the nearest office of your service provider (Glo or 9mobile) to register/link your NIN.
Go with NIN and your SIM pack or call the customer care line of your service provider.
9mobile said it is making effort to develop a system that would make things simple for its customers.
You can check your NIN status by dialling *346# from your 9mobile line.
NB: NIMC said that Nigerians already enrolled in the NIMC scheme but who have lost their NIN should dial *346# to retrieve the NIN. It also said that USSD code is available on MTN, Airtel, Glo and 9mobile.
