I am using this site for more than 2 years ans still this is my best site to get free recharge. it give free recharge by various campaign like install apps, referrals, contest etc. you can easily earn 100s of free recharge in a month by only giving few min daily on this app. it also give the daily credits for login in app. its referral campaign has changed a lot from starting of this website.
In starting they give approx rs 100 to 250 for each referral but now they pay only rs 40-50. I have done plenty of mobile recharges for free using mCent. mCent is designed for searching newly launched android app and they pay you for each downloaded app. from rs 1 to rs 50.The concept of Mcent is similar to that of Taskbucks . both pay us free recharge
