I've registered my sim twice and is not activated

Sorry bro, is it a new sim? If yes, what happened? Did you start using it for calls, SMS or browsing after you registered it? You can also chat with Zigi on https://www.mtnonline.com and she'll connect you to a Support Specialist that'll check on it and then help you resolve it. I can feel the pain and stress you've gone through.

Sone times the problem is with the NIN number. Make sure it is validated. You can check by downloading the nimc app Form playstore.
