LTE subscribers continue to use more mobile data and buy larger data plans than 3G subscribers. According to new research from Mobidia Technology and Ovum, Apple iOS and Android smartphone users surpassed the 10 GB per user per month mark in December 2014 in terms of both Wi-Fi and cellular usage, consuming on average 10.9 GB and 10.3 GB respectively. However, many also continue to purchase plans that are much larger than needed to cover their monthly usage: 53 per cent of 3G smartphone subscribers and 48 per cent of 4G smartphone subscribers used only half or less of their data plan in December 2014. LTE subscribers also continue to rely on Wi-Fi as their primary wireless connection, with over 80 per cent of their monthly data consumption occurring on mostly Wi-Fi networks at home and at work. The report also notes that LTE has become one of the fastest-growing mobile technologies in history, with a total of half a billion global subscribers expected this year. Report
