Some weeks ago MTN had network issue that made their network incredibly slow, those using internet connection experienced it the most. I even switched to GLO because of how slow internet connectivity was on MTN.
Due to inconveniences caused by the network issues, MTN have started rewarding their customers with free 100MB data. The good news too is that you don’t have to do anything special other than to insert your MTN sim if it wasn’t in your device before now. Also if you’ve not gotten the SMS yet and your phone is on, just dial *131*4# to confirm your data balance because there’s high chance it’s already been credited.
But if you don’t see any 100MB just wait patiently for it.
The 100MB giveaway from MTN is a compensation for the slow internet connectivity that their customers had to endure because of their network issues .
