Extended information
The CDMA2000 standard is also operated in more than 50 countries and regions, including the United States, South America, Japan, South Korea, China (including Macau and Taiwan) and other countries and regions operators are operating CDMA2000 networks.
So among the three 3G standards, TD-SCDMA has the smallest coverage, and there is no 3G data roaming (because only China has a commercial TD-SCDMA network in the world).
However, in the next LTE network standard, TD-LTE is relatively in a better situation than the current TD-SCDMA. Operators in some countries have begun to build FDD-LTE/TD-LTE dual-band networks. , although the number of operators currently supporting TD-LTE is far less than the number of operators supporting FDD-LTE, it can at least be considered international.
