The basic idea behind a Call Shop business is to have a place where customers can make local, long distance or international phone calls. The main sources of revenues will come from the minutes customers are going to spend on the phone. So it all depends on the rates that you are going to setup, just make sure that they are lower than the ones offered by the providers of international call services.
What we do best - World-Link provides local, national and international long-distance calling and also broadband access to its switches at vastly reduced rates, allowing our customers to realise huge savings when making calls.
