Mainland numbers can't receive Macao verification code.

The failure to receive Macao's mainland number verification code may be caused by the following reasons:

1. Mobile phone number input error: When inputting verification code, the mobile phone number input error is one of the main reasons why the verification code cannot be received. Please carefully check whether the entered mobile phone number is correct.

2. Network problem: Macao SMS verification code may need a better network connection to receive it. Please make sure your phone is in a good network environment, or try to switch to another network environment.

3. SMS settings: Some SMS settings may block or filter verification code messages. You can check your SMS settings to make sure that SMS is not blocked or blocked.

4. Operator problem: If you use the mainland mobile phone number in Macau, you may not receive the verification code because the operator blocks or restricts the SMS function. You can contact your operator to find out if there are similar restrictions and try to delete or change the relevant settings.

5. Technical problem: If none of the above methods can solve the problem, it may be because of technical problems that the verification code cannot be received. You can try to contact relevant technical support and ask for help to solve the problem.

If the above methods can't solve the problem, I suggest you contact relevant technical support for help.
