Historia hariri

 
IBM Simon(1994)[3]

Simu ya kwanza kuuzwa ambayo inaweza kuitwa simujanja iliitwa "Angler": ilitengenezwa na Frank Canova mwaka 1992 wakati akifanya kazi IBM.[4][5][6]

Toleo lililoimarishwa zaidi liliuzwa mwaka 1994 na kampuni ya BellSouth kwa jina la Simon Personal Communicator. Pamoja na kupia na kupokea simu, simu hii iliweza pia kutuma nukushi na barua pepe. Simu hii ilikuwa na ramani, kalenda, kitabu cha namba za simu, saa, n.k.[7]

Neno "simujanja" halikutumika hadi mwaka mmoja baada ya kutolewa kwa simu hiyo.
