Can Hong Kong calling cards send and receive short messages in China?

Hong Kong calling cards can send and receive short messages in China, but you need to enter the phone number in a standard format. The specific operation mode is as follows:

1. Enter the phone number of the receiver in the SMS edit box, for example, the Hong Kong phone number starting with 852.

2. Enter the prefix "+86" before the number, and then press Enter.

3. Move the cursor to the text part of the edit box to write a short message.

4. Finally, press the send key.

It should be noted that in Chinese mainland, the text content of short messages must comply with national laws and regulations and must not contain illegal content. At the same time, because international SMS involves many factors such as mobile phone number and service provider, if you have related problems or encounter difficulties, you can consult the corresponding mobile phone manufacturer or communication operator.
