MTN 20% data bonus offer is available to all MTN users and it involved IMEI tweaking, just like the MTN 100% data bonus. This mean you get 12GB when you buy 10GB data from MTN or 1.8GB when you buy 1.5GB for 1000 Naira.
This is an alternative for those who find it difficult to activate the MTN 100% data bonus.
If you buy some brands of smartphone from Infinix or Tecno, you will automatically enjoy this bonus too whenever you subscribe for data. But assuming you don't get this offer, you need to apply below tweaks to activate the 20% bonus data.
Insert your New or Old MTN SIM card now into an Android device and tweak the IMEI below to get MTN 20% Data Bonus For 3 Months
THE IMEI: 35166408560****
Use any four (4) digit number as the last four numbers. Once you succeed in Imei tweaking, you will receive a successful message from MTN within a period of time saying; "Congratulations! Your smartphone has been activated to enjoy 20% bonus on any data you buy for the next 3months."
