Research firm In-Stat said that more than 15 percent of people carry two wireless phones.
"Eighty percent of people who have a camera-phone regularly carry a digital camera, 75 percent of smartphone users also carry a PDA, and more than 50 percent of multimedia phone users also carry an MP3 player," said In-Stat analyst Bill Hughes.
"It is important to understand this customer behaviour if the wireless industry is to offer commercially successful solutions."
The In-Stat survey found that only 43 percent of respondents, all of whom are business users, stated that higher productivity would be obtained with a smartphone.
In addition, many wireless users consider the additional capabilities offered with a wireless device to be a gift for becoming or remaining a subscriber, and not as a tool that is enhanced with real-time data.
Almost half the respondents believe that they will carry fewer devices by owning a smartphone.
