How MTN SmoothTalk Plus works
Simply dial *401# or send 401 to 131 and migrate to MTN SmoothTalk plus.
From 12:00am (00:00) on Day 1, MTN will begin to record and accumulate the duration of all the National calls that you make.
For the first one minute of calls that you make, combination of MTN-to-MTN and MTN-to-Networks calls will be charged at 40 kobo per second
As soon as you make a total of 60 seconds call, your MTN-to-MTN and MTN-to-Other networks calls will now be charged at 15 kobo per second for the rest of the day.
At 11:59pm (23:59), your total call duration will be re-set to 00:00 minutes and your national call rate will return to 40 kobo per second.
At 12:00am (00:00) on Day 2, the same will happen - after your first one minute of call at 40 kobo per second, your MTN-to-MTN calls and MTN-to-Other Networks will be charged at 15 kobo per second for the rest of the day.
