is a mobile phone a touch tone phone
Push-button telephone The international standard for telephone signaling utilizes dual-tone multi-frequency (DTMF) signaling, more commonly known as touch-tone dialing. It replaced the older and slower pulse dial system.[17][18] The push-button format is also used for all cell phones,[12] but with out-of-band signaling of the dialed number.
Smartphone The first commercially available device that could be properly referred to as a "smartphone" began as a prototype called "Angler" developed by Frank Canova in 1992 while at IBM and demonstrated in November of that year at the COMDEX computer industry trade show.[5][6][7] A refined version was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator. In addition to placing and receiving cellular calls, the touch screen-equipped Simon could send and receive faxes and emails. It included an address book, calendar, appointment scheduler, calculator, world time clock and notepad, as well as other visionary mobile applications such as maps, stock reports and news.[8] The term "smart phone" or "smartphone" was not coined until a year after the introduction of the Simon, appearing in print as early as 1995, describing AT&T's PhoneWriter Communicator.[9][non-primary source needed]
