[quote=GUEST5673,525540]I am afraid that your cellphone may not support China 4G service no matter which telecom operator you choose. China 4G mode is TD-LTE. It's totally different from other countries in the world. Your cellphone may not support China Mobile's 3G service. It's TDCDMA, which is not compatible with other countries. So you may use China Unicom or China Telecom. China Unicom supports WCDMA and China Telecom, CDMA. It depends on which mode your cellphone supports. According to what I know, you may buy separate data packages from the telecom operators.[/quote]
