Yes, China uses GSM, but with some unique characteristics.
GSM in China
- China Mobile, the largest mobile operator in the world, primarily uses TD-SCDMA (Time Division Synchronous Code Division Multiple Access) technology, which is a 3G standard developed in China.
- China Telecom and China Unicom utilize GSM (Global System for Mobile Communications) and WCDMA (Wideband Code Division Multiple Access) for their 3G networks.
- China Mobile also offers GSM services, particularly for older devices and in areas where TD-SCDMA coverage is limited.
Unique Aspects of GSM in China
- Frequency Bands: China uses different frequency bands for GSM compared to other countries.
- SIM Cards: China uses SIM cards with a unique format and specifications.
- Roaming: Roaming for GSM devices can be challenging in China due to the prevalence of TD-SCDMA.
Conclusion
While China primarily uses TD-SCDMA for its 3G network, GSM is still used by some operators and for older devices.
