What is international short message?

1. SMS international services include SMS international roaming service and international interoperability service. 1. International short message interworking service: refers to the service that mobile users of China Telecom can send and receive short messages with users of operators outside China (including Hong Kong, Macao and Taiwan operators). 2. SMS international roaming service: refers to the service that China Telecom mobile users send and receive SMS with domestic or foreign operators when roaming in networks other than China Telecom (including roaming to Hong Kong, Macao and Taiwan). 2. As can be understood from the above definition, the international roaming service of short messages emphasizes that the places where mobile users of China Telecom can use short messages are different countries and regions, while the international interworking service of short messages emphasizes that the users that mobile users of China Telecom can contact through short messages belong to multiple networks in multiple countries and regions. Therefore, according to the users' different networks and users who send and receive short messages, the international short message service can be divided into the following three situations: 1, China Telecom mobile users roaming to Hong Kong, Macao and Taiwan, overseas mobile networks exchanging short messages with users within the network and users between networks; 2. Mobile users of China Telecom send short messages to Hong Kong, Macao and Taiwan users and overseas operators in China Telecom network; 3. Mobile users of China Telecom roam to Hong Kong, Macao and Taiwan and overseas mobile networks, and send short messages to local mobile users and users in other countries and regions. 4. In the above three cases, China Telecom's CDMA short message international service is different in usage mode, usage scope and tariff. Thank you for your interest in telecom products.
