I guess we haven’t heard the last of Tweaking to get Free Data from mobile networks. And in this recession period where getting free data would save you money and make you happy but getting a whooping 5GB from Airtel with just 0.0 naira. Then, i think you would be able to download most of the things you’ve had in mind but can’t risk using your paid data which you can use to do other things.

And I know imei tweaking shouldn’t be knew to most of us again because it’s been long we’ve been doing this to get free data or few benefits from those new smartphones that are being released with free awoof but can only get it unless you buy the smartphone which makes us change our imei number to look like the smartphone so we can also enjoy the benefits.Free Airtel 5GBWould have shared my personal screenshot of me getting it but i tweaked it on my nokia torchlight so i got the screenshot from a fellow blogger which confirmed it worked and you can trust me on that.Simply tweak your Android imei with the IMEIs below to get the free Airtel 5GB:
861143032391024

Make sure you change the last 4 or 5 digits from the above imei number provided and use imei analyzer.
After the successful tweaking, send the imei to 232
E.g S861143032399041 to 232 and you should receive a Valid message and if you don’t then you tweak another IMEI

Then, text JOIN to 141 and you should receive your own free 5GB, valid for a month at no cost.
