This was the message MTN sent to all their SME data users concerning the coming development to take up soon:

“Dear Customer, from Dec. 7, 2017 the following prices will apply to MTN SME Data Share 10GB-N6,500; 20GB-N13,000; 50GB-N30,000. Thank you for choosing MTN.”
This new coming change will update the regular N600 for 1GB and all resellers will only be able to access the new changes. So, it’s advisable for all resellers to hurriedly buy data in bulk for the next 3 months before the coming change takes effect.
