As smartphone penetration increased over the past year, so has consumers’ data usage, which went from 5.5 GB per month in Q4 2012 to 6.6 GB per month in Q4 2013. While this increase in data usage came from a variety of activities, a key driver has been the adoption of streaming music services such as Pandora and iHeart Radio.
Apple's introduction of two new smartphones, the iPhone 5s and iPhone 5c, as well as expanding to other carriers such as T-Mobile most likely helped contribute to the increase in smartphone users.
