 We start to advertise to the all the municipalities of the area. Yes, in the press, I'm sending a wrought communication and advertising, hey, we are able to provide wireless services to the rural area that is a problem. They are used to write the newspaper, we don't have internet here and blah blah. The first way to have customers for us was the customers telling other people how happy they were with our service. Self-advertisement network. Without providing discount, 80% of our customers came by other customers.
