Hi there! I'm Ameerah Mason from England. I am a Professor. In a business, the best alternative of cellular phones is two way radios which have many benefits. As there are many two way radios are available in the market, it is significant to choose such a digital two way radio that can work in both digital and analog modes. Digital radios offer you the benefit of talking with team members individually with better clarity, and better battery life. But not all digital two way radios for sale are designed equally, some digital two way radios may not be compatible with other manufacturer's two way radios.
