What are the ways to inquire about international roaming charges?

Hello, telecom users can send the short message code "GJMY+ Pinyin initials of the country to be roamed" to 1000 1 for inquiry. For example, users who query the United States can edit GJMYMG and send it to 100 1 to query roaming information. Users can also log in to China Telecom and roam official website to inquire about relevant information.
