MTN Data Subscription Plan Code

If you want to subscribe to an internet data plan from MTN Nigeria, you just need to have sufficient credit on your phone, have a registered MTN sim and dial the USSD code.
Here are the data plans I know and their corresponding data plan for MTN Nigeria:
1. 10MB = NGN100 = 24 Hrs = *104#
2. 25MB = NGN400 = 7 days = *105#
3. 100MB = NGN1000 = 30 days = *106#
4. 500MB = NGN2000 = 30 days = *110#
5. 1GB = NGN3500 = 30 days = *111#
6. 3GB(9PM-6AM) = NGN2500 = 30 days = *102#
7. 3GB(9AM-9PM) = NGN6000 = 30 days = *107#
8. 3GB(Fri9PM-Mon 6AM) = NGN3000 = 30 days = *108#
9. 5GB = NGN8000 = 30 Days = *101#
