I'm not up to 18 so I can't register a new sim so please I want to know if I can use another person's sim that has not been linked to any nin to register my own...
I want to know link my nin card to my mtn line but it say that I have already link another nin card to it.
How can I link my personal
Nin to this mtn number...
You can retrieve your NIN by dialing *346# on the phone number you registered with and it will cost you N20. To link your NIN, please dial *785# and select 1
