How to send short messages when roaming internationally?

When roaming to overseas mobile networks, SMS is sent in the same way as in China. Just enter the other party's number directly in the receiving number column. For example: (1) If you send a text message to Chinese mainland's mobile phone number (excluding Hong Kong, Macao and Taiwan), please enter the other party's mobile phone number directly. (2) If sending SMS to a mobile phone number outside Chinese mainland, you need to enter: 00+ country (or region) code+mobile phone number. (Example: In the United States, using CDMA network to send short messages to mobile phone users in Hong Kong (area code: 852) requires entering "00852 mobile phone number".
