What does Feature Phone mean?
A feature phone is a type of mobile phone that has more features than a standard cellphone but is not equivalent to a smartphone. Feature phones can make and receive calls, send text messages and provide some of the advanced features found on a smartphone. Feature phones were primarily designed for consumers who want a multifunctional mobile phone but aren't willing to pay the higher prices associated with true smartphones.
Feature phones are also known as dumbphones, a retronym to contrast them with smartphones.
