| Saily | China Unicom | 5G | 4G LTE, 5G in places | 4G LTE, 3G in gaps | 5G |
Peak vs Off-Peak Congestion
Every mobile network in China carries more traffic in the evening and over lunch, and commute hours crowd the towers near transit hubs. All five providers share those towers, so congestion hits them equally. Schedule large downloads and video calls outside those windows.
Indoor Signal Quality
Building penetration varies by carrier and frequency band in China. Low-band carriers (700 MHz) penetrate buildings effectively. High-band 5G (mmWave) requires line-of-sight and struggles indoors. Mid-band 4G LTE provides a balance of speed and indoor reach. Hotels, restaurants, and shopping centers typically maintain strong signal quality.
Throttling and Fair Use
HelloRoam and Holafly unlimited plans in China run at full 5G speed until the daily fair-use threshold. After the threshold, speeds reduce. Maps and messaging still work at throttled speeds. Video streaming and large file downloads do not. Fixed data plans from HelloRoam, Airalo, Saily, and Nomad run at full speed until the data allowance is completely used, then stop entirely.

Advice
China Coverage Tips
Seasonal Congestion
Network congestion increases during peak season in China (Apr-May, Sep-Oct). Spring and autumn offer best weather; avoid Golden Week (Oct 1-7) and Chinese New Year for extreme crowds Tourist-heavy areas experience slower speeds during peak months. Consider upgrading to a larger data tier during peak season to compensate for potential throttling.
