Weibo SMS verification code exceeded the upper limit, and it was the same the next day.

Mobile phone number is restricted, sms channel fault, mobile phone operator problem, etc. Details are as follows:

1. Mobile phone number is restricted: If the wrong verification code is entered for many times, Weibo may restrict the mobile phone number, resulting in failure to receive verification code normally. At this point, you need to wait for a while, or contact Weibo Service for processing.

2. sms channel malfunction: Sometimes sms channel may malfunction, which makes it impossible to receive the verification code normally. At this time, you can try to change your mobile phone number, or wait for Weibo to fix the fault.

3. Mobile phone operator problem: If the mobile phone operator fails or the network is unstable, it may also lead to the failure to receive the verification code normally. At this time, you can try to change the network environment or contact the operator for processing.
