Hi Byoungguk,
One of the things that makes Sinch a leader in the mobile messaging market is our vast number of direct connections. Over the years we have built relationships with suppliers and operators that allow us to reach all four corners of the globe. Sinch currently serves over 200 destinations and thousands of networks, including the countries you referenced: South Korea, the United States, China, Japan, and Vietnam.
