The problem is that not everyone is eligible for the 100% double data plan, But you don't need to worry am going to guild you, on how you can be eligible for the double offer.
How to be eligible for mtn 100% double data plan.
To be eligible you need to tweak your phone's imei to the imei that offers the 100% double data below is the imei ;
352262070180146
Change the last 3 digit and make sure you use imei analyser to get a VALID imei.
Example I changed "352262070180146” to “352262070180245” before I was eligible for the offer.
After tweaking, in less than 5min or in some cases more than 5min you will get a message that reads “Welcome to MTN Family…..” if you didn't receive this message kindly retweak your imei again until you receive such message
Now :
Migrate to MTN Better Talk by dialling 1232*6# or send BT to 131
And Dial 1311# to buy any MTN DATA of your choice and the data will be doubled.
