Exceeded the upper limit of receiving SMS with mobile phone number.

1. It is possible that the platform limits the number of times that the mobile phone number can obtain the verification code in a fixed period of time. If verification codes are frequently obtained in a short time, they will not be collected after exceeding the number allowed by the platform.

2. The verification code message is intercepted by mobile phone security software. Check whether the mobile phone is equipped with security software, and check whether the verification code message is intercepted.

3. When there is traffic jam or other abnormal situation in the SMS gateway, our mobile phone may not be able to receive the verification code message normally, so we can wait for a while and try to get the verification code again.

4. If you use a domestic mobile phone number abroad and send the platform verification code through a domestic operator, it may not be received normally due to geographical conditions.
