How to send SMS after opening international roaming

1, sending international roaming SMS is the same as sending domestic SMS, the only difference is that the number input needs to be changed.

2. Enter the following information in the sent number: international prefix (00)+ country code+customer number or international prefix (+)+country code+customer number.

3. Because the country code of China is 86, if you send a short message to a domestic user in China, you can write the number like this. +86 * * * * * * * or 0086 * * * * * *, * * * * refers to the mobile phone number of the receiver. However, because it is in China, the previous +86 message is generally omitted, so if you send an international short message, you must add an international code. The specific international code can be found through Baidu.
