Deloitte's third Global Mobile Consumer Survey (GMCS) provides a unique insight into the mobile consumer behaviour of 37,600 respondents across 20 countries. In the UK, we can draw some fascinating and unique insights based on responses from 4,000 UK consumers, double the amount from 2012. The survey's scope ranges from quantifying ownership of devices to understanding how these are being connected and used. Other areas covered are: 4G, triple-play and quad play, dynamic pricing, apps, tariffs and billing, digital content and apps and mobile advertising.
