MTN is currently giving out free 150mb data to it's customers. This isn't actually a cheat and the data does not come with any hidden charges.
The purpose of the data is actually to download theMymtnApp but you can use the data to browse, stream, download and do anything you like for a validity period of 3days.
How to Get The Free MTN 150MB Data
Getting the data is pretty easy and straight forward, all you need to do is to text Myapp
If your SIM is eligible, you will receive a text message like the one beneath:
Dear customer, You now have a bonus of 100MB valid for 3days for downloading MyMTN App. Kindly dial *559*4# to check balance.
If you get an error message like the one beneath, you can try again or get another sim.
Y'ello, your subscription to Myapp has failed. Please retry by sending Myapp to 131
As I said, the data is valid for just 3days and it works irrespective of your current tariff plan.
Enjoy while it lasts!
