Why can't my mobile phone receive other verification codes except Unicom's verification code?

According to the information you provided, if you can't receive SMS or verification code, there are several 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;

Hardware factors cause your mobile phone to receive short messages abnormally, so I suggest you change your mobile phone for detection;

After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

If the above problem does not exist, please contact the manual customer service where the number belongs to handle this problem.
