WeChat SMS verification code, why can't it be sent out?

Hello, if you confirm that your WeChat is bound to this number, 1. If you mean that you can't receive the SMS verification code, there may be the following reasons:

1 Your number is currently in an abnormal opening state, such as loss reporting due to downtime. I suggest you open this number and try again.

2 Your mobile phone has put the short message into the trash can, or the mobile phone security software has intercepted the short message, you can look in the short message trash can first or the software has intercepted it;

Due to the large number of users, the speed of sending short messages is slow. You can try again later.

Your mobile phone receives short messages abnormally. I suggest you change your mobile phone for testing.

2. If this is not the case, it is suggested that you can contact Unicom's manual customer service for verification. The actual situation is subject to local policies.
