Why can't Zhihu receive the verification error and try again?

Mobile phone failure or setup problem.

Due to the following circumstances:

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 you can't receive the verification code and SMS when you stop. It is recommended that you restart your mobile phone after paying the fee.

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.

SMS verification code is an effective verification code system by sending verification codes to mobile phones. Both large websites, especially shopping websites, have the verification code function of SMS, which can ensure the safety of shopping more accurately and safely and verify the correctness of users.
