How to solve the failure of WeChat friend verification?

Hello, how to solve the failure of WeChat friend verification? First, update to the latest official version of WeChat. Second, the mobile phone number is abnormal. The mobile phone number used for friend verification is bound to an inactive account or an illegal account, so you can't use this mobile phone to unblock other accounts. Please change another mobile phone number and try the operation again. Third, the virtual operator number does not support unsealing. Wechat does not support unsealing with virtual operator number. Please use the mobile phone number registered by the operator to unseal it. Fourth, the micro signal does not meet the requirements (trusted micro signal assisted unsealing). This prompt indicates that the friend's mobile phone number you entered does not meet the conditions for assistance in unsealing. Please re-enter other mobile phone numbers that meet the auxiliary conditions to unseal. The invited micro signal must meet all the following conditions: 1. The micro signal has a bound bank card and a bound mobile phone number; 2. The registration time is more than 6 months, and it has been used normally (the blocked or frozen account is not used normally, and the user will prompt "The micro signal does not exist or the micro signal does not meet the requirements, please re-enter" after input); 3. The number of auxiliary verifications has not been exceeded recently (1 time/month, 2/June, 3/year); 4. At present, it has not received any invitation for assistance from other countries; 5. The account number of the auxiliary unsealed account has not been unsealed in the last year.
