While the steps above should help you unblock your NIN-barred line, there can be occasional hiccups. Here’s how to troubleshoot some common problems:

  • Error message after entering your NIN: This could indicate a few things. Double-check that you entered your NIN correctly, including all 11 digits. There might also be a temporary issue with the network’s system. Try again later or contact your network provider’s customer care for assistance.
  • NIN verification failed: If your NIN verification fails, it could be because:
    • Your NIN is not yet activated by NIMC. Allow some processing time after registering for your NIN.
    • There’s a mismatch between the name on your ID and the name registered with your NIN. In this case, you’ll likely need to visit a store to update your SIM registration details.


Getting your NIN-barred SIM card unblocked might seem like a hassle, but with the right information and a few simple steps, you can get back to using your phone without any problems.
