What is a big button phone, and how is it different from a regular phone?

Big Button Phones have larger, clearer keycaps and a simpler layout than most regular phones. Numbers are printed with high contrast, and spacing that could ensuring that confusion about calling the wrong number is decreased. The vast majority of the models don't have complex menus; hence, basic tasks such as placing a call, selecting pre-set memory buttons, receiving a call, and leaving a call are handled by just one button with one particular problem.
