Organisations need to introduce policies to manage and measure employee mobile usage as rising data traffic and smartphone use hits corporate costs.
IT analyst firm Quocirca found that over 40% of businesses believed mobile costs needed to be brought under control within its organisation.
Rob Bamforth, the report co-author and principal analyst at Quocirca, warned that employee use of mobile e-mail, web browsing and particularly social media applications on corporate smartphone devices have driven mobile bills up.
Data roaming is the area to monitor, said Bamforth. "We will continue to see data charges while roaming, which can hit businesses and individual users quite hard. No-one really knows how much in terms of megabytes they're using when surfing the web," he said.
Bamforth advised organisations to implement policies to measure and value mobile billing for individual employees concerning the business use of mobile phones.
"It's always difficult to say how much data is being transferred. It's an impossible thing to pre-define. A better way of metering as you use might become prevalent in the future," added Bamforth.
Mobile internet browser firm, Opera Software, has reported that global mobile data traffic through its browser has risen 134% over the past year.
According to a survey of 300,000 of Opera Mini users, Opera found mobile data traffic rose 15% between September and October this year alone.
