Have been using MTN network for over 7 years now and am so satisfied with their network provider, vast coverage,their customer service response after waiting for some times while enjoying musicals.
I use MTN network for my daily business transactions with a very strong network in my area.
Although MTN data subscription is on the high side and the more I recharged,the more my data subscription bundle on *121# increases but in all MTN is doing wonderfully well.
