The first smartphone was the IBM Simon; it was designed in 1992 and shown as a concept product that year at COMDEX, the computer industry trade show held in Las Vegas, Nevada. It was released to the public in 1993 and sold by BellSouth. Besides being a mobile phone, it also contained a calendar, address book, world clock, calculator, note pad, e-mail client, the ability to send and receive faxes, and games. It had no physical buttons, instead customers used a touchscreen to select telephone numbers with a finger or create faxes and memos with an optional stylus. Text was entered with a unique on-screen “predictive” keyboard. By today’s standards, the Simon would be a fairly low-end product, lacking a camera and the ability to download third-party applications. However, its feature set at the time was highly advanced.

In 1997 the term ‘smartphone’ was used for the first time when Ericsson unveiled the concept phone GS88, the first device labelled as ‘smartphone’.
