China has over 1 billion mobile subscribers, with the three main carriers (China Mobile, China Unicom, China Telecom) dominating the market. 3G adoption is still low, accounting for under 10% of subscribers. SMS and basic feature phones are still widely used, even among youth. The market is fragmented across China's 31 provinces, and most users are prepaid with little subscriber data available. Mobile internet use is growing rapidly along with larger phone screens. Future revenue growth is expected from mobile data and applications, though monetization remains a challenge.
