You can get alot of airtime by taking a survey. Online with your mobile phone mCent is the easy way to get free airtime on your phone. I have being using it since 2010, the reason why i live to talk about it now is because they have done a grate job since then, and alot of people are using it, with millions of fans
TIP: if you have a two phone number try to register it so you will be geting airtel to those numbers insted of one. Don't scam, just togo
