I am roaming abroad, how can I send a short message to my mobile phone in Chinese mainland?

The premise is that users need to open international roaming services, and they can't send them without opening them. Of course, some calling cards have international roaming service by default, such as Unicom's prepaid card.

Sending international roaming SMS is the same as sending domestic SMS, the only difference is that you need to change the number input.

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

Because the country code of China is 86, if you send a text message to a domestic user at home, 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.
