How:

If your Glo line hasn’t been used for a long time, it may be deactivated.
Quick test:
- Insert SIM into another phone
- Dial a Glo code like
*777#
If no response, visit a Glo service center for SIM reactivation.

*996#
to check NIN status - Or visit the NIMC website for more options
7. Try SIM in Another Phone
This will help rule out if your phone is the problem.
- If the SIM works in another phone, the issue is your device.

8. Reset Network Settings
Restores your phone’s mobile config to factory defaults.
On Android:
- Settings > System > Reset > Reset Network Settings
On iPhone:
- Settings > General > Reset > Reset Network Settings
9. Contact Glo Customer Care
If all else fails, contact Glo support:
- Call 121 from another Glo line

Ensure your Glo SIM is properly registered, linked to your NIN, and placed in a supported 4G or 5G device. If none of these work, visit the nearest Glo office for SIM swap or reactivation.
