Analyst Gartner predicts mobile data services sales will grow 23% to $314.7bn in 2011 compared to sales of $257bn in 2010 as a result of worldwide mobile connections reaching 5.6 billion.
Jessica Ekholm, principal research analyst at Gartner, said smartphone and tablet sales are driving increased mobile traffic.
"Mobile data volumes will continue to grow as mobile data networks become faster and more ubiquitous, while at the same time the number of data users and data usage per user is expected to grow," she said.
Gartner predicts global mobile connections will reach 7.4 billion in 2015 with mobile data sales growing to $552bn.
The research firm said the growing number of mobile connections will put higher demands on communication service providers (CSP) to upgrade data networks and improve personalised data plans.
"What carriers currently need are innovative ways to increase data revenue while finding smart solutions to manage a growing demand in data," said Gartner research director Sylvain Fabre.
Vodafone's latest results reflected increased use of smartphones and data consumption within the workplace. Vodafone said 22% growth in UK data sales in the three months to 30 June 2011 was due to higher smartphone use and increased data traffic.
A report released by Ofcom shows mobile data services have increased "40-fold" over a three-year period, from 2007-2010.
Ofcom wants to cut the wholesale charges for connecting calls to mobile networks by 84% over the next four years from 4.18p per minute to 0.69p while mobile operators say wholesale charges should fall only to 1.25p.
In addition, the latest report by analyst Juniper Research warns mobile network operators (MNOs) may face a "seven-fold increase" in data delivery costs as a result of "inefficiencies in base station operations".
