About this episode
Nick Merrill discusses how his company Phreeli provides cellular service without requiring personal information beyond a ZIP+4 code.
Cellular providers need to know your location in order to deliver calls and text message to your phone. But it turns out that they really don’t need to know who you are to give you that service. They only need to know how to bill you – and that information can be at little as knowing your ZIP+4 code. Why do we give so much personal information to our mobile service providers when we don’t have to? Today, Nick Merrill, founder of Phreeli, will explain how he can give you top notch cell service and know almost nothing about you.
