The most dramatic observation from our survey is the surge in mobile data service usage: 48% of UK mobile users now use a data service at least once a month, up from just 30% last year. This increase is substantially all from the increased number of internet-centric smartphones (i.e. iPhone, BlackBerry and Android handsets) in the base. The internet-centric smartphones themselves had substantially no reduction in data usage penetration rates (all at 90%+) despite their volumes surging, with users from all age and socio-economic groups using them for data services. Data service usage penetration on a daily basis actually increased for Android and BlackBerry handsets. This supports our view that it is the nature of these handsets in terms of their ease-of-use for data services that is driving overall usage, and that overall data usage will continue to surge as they continue to diffuse through the subscriber base.
