Duck chat card can't receive verification code

The reasons why the duck chat card can't receive the verification code are network problems, wrong mobile phone number, registered mobile phone number, and the verification code is intercepted.

1. Network problem: You need a certain network connection to send the verification code. If the network is unstable or the signal is not good, you will not receive the verification code.

2. Wrong mobile phone number: If the entered mobile phone number is wrong, the verification code cannot be sent to the correct mobile phone.

3. Mobile phone number has been registered: If the entered mobile phone number has been registered by other users, you will not receive the verification code.

4. The verification code is intercepted: Some mobile phones may regard the verification code short message as spam short message or intercept short message, resulting in that the verification code cannot be received normally.
