If your SIM isn’t linked to your NIN in 2025, you’re at serious risk of getting blocked—calls, data, and even mobile banking can stop working. The problem? Many people don’t know how to properly submit their NIN on their network—or they submit it and get no confirmation.

How to Confirm If Your NIN Submission Worked
Here’s what I did to confirm it:
- Waited 24–48 hours after submission
- Dialed regular codes like
*310#to check if SIM was active - Called a number—if call connected, the SIM was active again
- Checked NIMC Mobile ID app to confirm my NIN was valid
Tip: If you don’t get a confirmation message, resubmit using a different method (e.g., app instead of USSD).
Troubleshooting: If Submission Fails or No Confirmation
- Make sure your NIN is valid (check via NIMC app or
*346#) - Try submitting late at night or early morning (less server congestion)
- Contact your network’s support on WhatsApp or Twitter
- Walk into a service center only if all else fails
Conclusion
Submitting your NIN doesn’t need to be stressful. Every major network now supports USSD, app, and web-based methods to get it done from your phone.
I tested all of them, and they all work—when the NIN is correct and valid.
If you haven’t submitted yours yet, now’s the time. Don’t wait for your SIM to be barred.
