MTN have quietly introduced an unlimited plan. The plan which goes for just N150 allows you to browse the internet or download unlimited for 24 hours. Unfortunately, this plan is not for everyone, you have to be eligible. To find out whether you are eligible for this plan, try activating the plan on your sim by dialing the code below. To activate, dial *567*59# and reply with 1. If you pay N150 daily for a month (30 Days), that's about N4,500. Nice.
