When I first interact with android mobile the first things in my mind comes is internet but for this I have to recharge my datapack in my mobile.
then one of my friend send me a link of an app called mcent.this app gives us recharge for free by doing some easy tasks after installing the mcent app.
I earn a lots of free recharge from it by reffer to my other friends and installing some apps from it.it is very easy.the UI of the app is reliable and the best part of this app is that u can recharge minimum 10 rs.Also u can gift recharge to ur friends.
I m just loving it and im using this app by 2 year and I still recharge from it.
If u have an android mobile dont think so much.just go for it
