This is how to check if your National Identification Number (NIN) is linked to your phone number.
Following the order by FG that all telecom operators should disconnect all sims not in sync with the National Identification Number (NIN), here is a quick tip on how to check if yours has NIN linked.
Just dial *346# and press 1
It is understood that the service costs N20 per dial.
Hint: Some people will still have NIN linked as long as they completed their registration appropriately even though they don’t have National ID Card (NIMC).
