MTN has now started giving away free 1GB of data to its users. Provided that the user downloads and installs the new version of the MTN app.
It's as simple as follows: download the MTN app here, install the app and login. You'll then be rewarded with a 1GB free data valid for 24hrs. This offer only works once per registered sim card.
This won't last forever. Enjoy it whilst it last. Thanks to MTN.
