HUGE passive income from your free SMS At first I was a little distrustful of the app but now I have received $600 in about 3 weeks The application sends SMS automatically, the company "buys" you the SMS that you do not use for the different actions they have to do. You can choose the countries to send, the price and set a limit per day. They have recently updated the app and improved some features. Be careful, use it only if your SMS are unlimited or if you have a lot to spare
