GigSky SIM service in China

GigSky’s service in China uses both China Mobile and China Unicom. If your mobile device does not support China Mobile’s TD-SCDMA 3G technology, you will be limited to a 2G Edge data connection. If you have a mobile device that supports China Unicom’s WCDMA 3G technology, you may have to manually select Unicom to get 3G service. Please refer to your device’s user manual for instructions on how to manually select a network operator.
