MTN Zone stuck at 40k/second? Here’s how to fix it
MTN Zone is the arguably coolest prepaid tariff plan on the network in terms of voice calls. With calls being charged as low as 4 kobo (0.04 naira) per second at off-peak periods, this plan allows you to communicate with your loved ones and business acquaintances without breaking your pocket.
