MTN came up with series of data and call bonus after they acquire Visafone for N47.5 billion Naira. During that period, they came up lot of affordable and reliable data.
I don't know but it seems MTN came up with data and cheap call rate for their user maybe as a compensation or so.
MTN didn't stop the N1950 Airtime and 100mb. Even up till now. MTN only reduced the way they advertise the package because they have other and lot of tariff and plans to advertise to the masses.
