In the post, I’ll be sharing with you how to send messages for free on MTN. Before I share with you this offer, you should know that this is not a tweak or cheat of any kind. However, it is a legit offer from MTN which lets you send messages to other MTN numbers for free. You should note that these free messages are only sent from MTN to MTN and not other networks.

To enjoy this offer from MTN, you need to Migrate to MTN Biz Class plan. And here are the steps to do so:
>Dial *406#, then select Tariff Migration
>You’ll be shown two options, MTN Biz plus and MTN Biz class, select 2 which is MTN Biz class.
>Confirm your migration process. And that’s it, you can now start sending free SMS from MTN to other MTN numbers.

This is a free offer from MTN that allows its customers send free SMS to other MTN numbers. However, this offer comes with some disadvantages. First of all, there is a limit to the number of messages you can send. Secondly, MTN Biz class has costly data plans higher than the normal. And above all, to migrate back to your previous tariff plan you have to wait for a 30 days interval, else you’ll be charged N100.

In conclusion, this offer is has only one advantage which is to send messages for free to other MTN users. And if you really like this you can migrate to the plan and enjoy, else run!
