MTN started double offer for all smartphones long ago which simply gives 100% data back for all data plans. Airtel also have decided to divulge their own double offer. I can’t say if it is strictly based on smartphone or just selected sims but if eventually it is based on smartphone, imei tweaking will be the best option.
To subscribe to the offer
Dial *496# to get 3GB for N1,000
Dial *437# to get 7GB for N2,000
Dial *438*1# to get 18GB for N4,000
The validity period is 30 days.
More updates is loading I’ll be dropping Airtel 5gb /10gb valid imei soonest so, stay connected.
