Mobile data has also been vital to du's mobile revenue growth and its importance is set to continue in its future strategy; in the third-quarter of 2012, revenue generated from mobile data totalled AED323 million, up 93.4% y/y. Mobile data revenue now accounts for 16.7% of du's total mobile revenue, up from 9.8% at the same time last year. The continued growth of mobile data revenue will be crucial, particularly as voice revenues come under pressure, whilst the country's large foreign workforce increasingly utilise internet-based services, to the detriment of international call and text services.
