Airtel is currently running a promo that will give users the chance to get 36GB of data plus a whooping N15,000 airtime when you get a Fero 1801 phone for just N6,000 only.
This was shared by Airtel official on
Facebook, saying:

Get 36GB data + N15000 airtime over 6 months when you get a Fero 180/1 phone for just N6000!


See How You Can Activate The 36GB Data + N15,000 Airtime On Airtel Network

* Locate any nearest Airtel store via 
the link here.Airtel Nigeria
* Buy one of the Fero 1801 phone and insert an Airtel SIM to get 36GB of data + N15,000 airtime automatically that valid for over 6 months.

I pray that the imei of one of the phones should be leak, so as to be able to tweak it and even get the data +Airtime without buying any phone. 
It's as simple as that. Please, Kindly drop your opinion about this.
