Please check whether your mobile phone is equipped with security software to intercept short messages, or whether the WeChat client failed to send a verification request, which made the short messages unable to be received. Secondly, if your mobile phone number blocks Monternet information on the operator side, it will lead to the inability to receive short messages sent by the system. At this point, please contact the operator to cancel.
When using the location code, open WeChat "Sweep" to scan the location code. For the first time, you need to enter the mobile phone number, ID number and verification code to bind with the health code. The green code passed, and the red and yellow codes failed. Place code is the only two-dimensional code given (generated) by the platform to key places, which identifies the location, name and other information of places. After the people scan the code, the platform automatically records the relevant information entering the scene, which is only used for epidemic prevention and control.
