Despite having 70% global market share, the so called 2G mobile phone that runs on GSM technology has posted negative growth for the first time in 2013. And it will account for only 48% of the mobile subscription worldwide in 2018, predicts TeleGeography. Migration from 2G to 3G and LTE is already well underway in much of the world, but the pace of the transition varies widely by region. The move from 2G technologies is most advanced in North America, where 3G and LTE accounted for more than 80 percent of wireless subscribers at year-end 2013, and are projected to reach 93 percent of subscriptions by 2018. In western Europe, just over 50 percent of mobile subscribers used 3G or LTE in 2013, a ratio that is projected to grow to 86 percent by 2018.
