MTN Zone Tariff Plans and Benefits
Some years back, MTN Zone used to be one of the best tariffs. At that time you can get call rate as low as 1k/s mostly at midnight or early in the morning.
This tariff plan enables users to perform MTN – MTN calls for the lowest 4k/sec and between 4k/s – 24k/s during the day.
The plan later degenerated to 40k/s and people opted out. Even though the tariff is still listed on Migration code (when you dial *123*2*7#),
MTN has finally discontinued it.
