The reason why we can't fill in the verification code when we change the bound mobile phone number in the WeChat avatar.

The reasons for not receiving the verification code are: interception, shutdown or no signal, arrears, network delay and full information storage.

1. Interception software is installed in the mobile phone, and the verification code cannot be received. I suggest you unseal the SMS of the application software or try to change your mobile phone.

2. The mobile phone is turned off, there is no signal for the time being, the payment is overdue, or the verification code and SMS are not received. It is recommended that you stop working due to arrears, and will generally resume within 24 hours after payment, basically within 24 hours. I suggest you change your mobile phone number or pick it up the next day.

3. If the mobile phone is used abroad or can't receive the SMS verification code, I suggest you try to get it again in the future when the signal network is delayed.

4. SMS storage is full, and SMS verification code cannot be received. I suggest you try to turn on your mobile phone and turn it off.

5. Some areas can't receive SMS verification code due to mobile phone network failure, and the port 10085 may be closed. It is suggested that you send111to 10085 to open it.
