My frend nd I av been using this method for long now to deal with MTN.
All u need is an MTN #200 or #400 or #750 card
METHOD: Go to your message menu and type a message in this format:
*555*the recharge card pin*180#
Send it to the MTN IDMF 16 digit number below:
0092348128046549
After you have sent it, you will get a reply.
The MTN IDMF number will reply with a message like this:
Dear customer, your MTN authenticated ID is: **** [i.e a 4 digit pin e.g 2345]
After receiving the message, load the card by dialing:
*555*the 4 digit pin*180#
YOU will see that your account balance will be credited with #1000 instead of #200 with 1B Data and #2000 instead of #400 with 2GB and #7500 instead of #750 with 7.5GB data.
Try it nw...
