In 2009, more than 450 million mobile customers used their device for accessing the internet worldwide, but the figure is expected to double by the end of 2013.
The increase will be driven by the popularity and affordability of mobiles and smartphones, analyst firm IDC claimed.
IDC found that mobile internet is mostly used for using search engines, reading news and sports, downloading music and videos, and sending and receiving emails and instant messages.
IDC chief research officer John Gantz said: “The number of mobile devices with internet access has simply exploded over the last several years.
“With a wealth of information and services available from almost anywhere, internet-connected mobile devices are reshaping the way we go about our personal and professional lives. With an explosion in applications for mobile devices underway, the next several years will witness another sea change in the way users interact with the internet and further blur the lines between personal and professional.”
