Following the directives of the Federal Government, telecommunication companies, (MTN, Globacom, Airtel, and 9mobile) have bar all outgoing calls from unlinked Subscriber Identification Module cards, SIMs.
Why your sim get barred!?
You might me wondering why your sim card got barred,. It’s simple because you haven’t linked your National identification number (NIN) to your line. That’s what I’ll be putting you through and after that you sim will be unbarred.
How to check your NIN
Simply Dial *346# on your phone to check your National identification number.
