I know you will be wondering "How" immediately you see the topic. Just follow me as you read below.
Eligible users are those that spent 45 - 180 days on the network without performing any chargeable.

Benefits

You will enjoy this for a period of three (3) months.

How it works

Re-activate your inactive MTN SIM, recharge a minimum of N100 and enjoy 2000% bonus on your first recharge for the period of three (3) months.
2000% (20X) bonus on recharge of N100 and above with maximum recharge of N1,000.

Bonus can be used for Voice, SMS and pay-as-you go data. 500% of the bonus will be used for Voice calls & SMS to all networks (that is the N500). And the 1500% will be used for Data. (That is 1.5GB) Which is N1500 for Data, in data form it simply stands for 1.5GB.

Now when you recharge with N200 you will get 1000% (N1000) for Voice, SMS to all networks and 3000% (N3000) for Data = 3GB. 1500 + 1500 = 3000% in Data form it stands for 3GB.

The more higher you recharge the more higher you get.
Note: you will continue enjoying this for complete three (3) months.
