MTN has been doing me well since I started using them for my delivery work. The network is strong even when I'm moving around Zaria, and their data plans are reasonable for the price. My only gripe is going to their Sabon Gari branch — I waited almost 45 minutes just to recharge my line when their staff were just sitting down. To be fair, everything else works fine, but e no easy when you're trying to make money on the road and lose that much time. Overall sha, I won't complain too much.
