MTN network has been treating me well for years now. My data steady, calls clear, and the service na solid. To be fair, I went to their Abeokuta office last week to sort out my billing issue and I spent almost two hours waiting before somebody attended to me. That part pain me small because I had work to do. But apart from that one thing, e no easy to complain about their services — they are reliable and the prices reasonable compared to other networks.
