How do I send text messages when my mobile phone is roaming abroad?

1. If you send a text message to a mobile phone number in mainland China (excluding Hong Kong, Macao and Taiwan), please enter the other party’s mobile phone number directly. 2. If sending a text message to a mobile phone number outside mainland China, you need to enter: 0country (or region) code+mobile phone number. (Example: When using a CDMA network in the United States to send text messages to mobile phone users in Hong Kong (area code: 852), you need to enter "00852 mobile phone number").
