Enterprise SMS in China: Market Overview
China has the world’s largest mobile subscriber base exceeding 1.6 billion connections. Enterprise SMS is tightly regulated, with carrier-direct routes essential for reliable delivery to China Mobile, China Unicom, and China Telecom networks.
Key Mobile Operators in China

Regulatory Framework for SMS in China
The telecommunications and data protection landscape in China is regulated by MIIT (Ministry of Industry and Information Technology). Compliance with local A2P SMS regulations is not optional — non-compliant traffic is actively filtered at the carrier level and can result in route blocks, financial penalties, and reputational damage.
All A2P SMS must be sent through licensed carriers. Foreign businesses must partner with a licensed local SP (Service Provider). Strict content filtering is applied by carriers.
SBS Telecom’s Compliance & Regulatory Affairs team continuously monitors regulatory changes in China and all markets we serve. Our clients benefit from proactive compliance guidance at no additional charge.
