For some months running, Airtel data plan of N1000 for 3gig has been a big life saver especially for Android users as it has been confirmed that it doesn't consume data excessively like the one of N1500 for for 3gig does. It is also a better alternative to glo N1400 for the same 3gig.
What if I told you, that same amount of N1000 could get you 4GIG of data plus extra N1000 airtime to call your friends and loved ones, using that same Airtel data plan for 3GIG but slightly different procedure. Without wasting much time, let's go straight into business
How to Get Airtel 4gig Plus N1000 airtime
• Get an Airtel sim, it works on both new and old sims.
• Also get Airtel N1000 recharge card • Android phone that has its IMEI changed to BB10 IMEI. MTK devices like Techno,Infinix , Gionee, Innjoo, etc gives a better result.
