This is definitely what we want from MTN its is nice step to start with in this new year. MTN is dashing out free 4GB to the subscribers as a happy new year gift and means of welcoming their subscribers to the year 2017.
From the message I received from them, it says
I do not know if you also receive the same message, but to be sure if you have received your free 4GB dial *559*444#.
Let us know if you did via the comment section.
