摘 要：All Asia-Pacific countries have launched 4G services, which are slowly replacing 3G, as they are four to ten times faster. The Asia-Pacific is likely to have the highest volume of smartphone shipments, with revenue of the region’s mobile operators totaling US$500 billion in 2013, making it the world’s fastest-growing regional mobile market. SMS over the internet such as WeChat, LINE, KakaoTalk, Whatsapp and Viber have replaced traditional SMS among Asians as they provide lower or no charges, unlimited texting and rich features such as location sharing, emoticons or interesting animation. Although more Asia-Pacific internet users are web searching on smartphones and tablets Adobe estimates the vast majority of website visits are still done on a PC. The outlook for the mobile sector is positive, as smartphones with higher internet speeds are likely to be introduced to meet the demands of internet users and gadget lovers.
