UK consumers are using 4G mobile broadband for a variety of purposes, it has been claimed.
Fotis Karonis, Chief Technology Officer at EE, said that although a "large proportion" of activity on its 3G network is web browsing, other activities are also popular.
These include shopping, watching movies and catching up with TV - activities which would previously have required a fixed-line broadband connection, he stated.
"It is a real evolution, with a quarter of our customers now spending more than three hours a day on the mobile internet," Mr Karonis added.
"What is really interesting is that with 4G upload speeds five times faster than home broadband, we are seeing social media use becoming more mobile and transforming faster than had been imagined."
He said that, for the first time in the UK, the amount of data uploaded onto EE's network has surpassed downloads at major events such as the London Marathon and Baroness Thatcher’s funeral.
Mr Karonis claimed 4G users are "intuitively taking advantage of increased upload speeds".
"We predict data volumes over social media sites will increase tenfold by 2015," he added.
