Unicom mobile phone business hall can't receive SMS verification code.

When logging in to Unicom's mobile phone business hall/online business hall, you may not receive the random password for the following reasons:

1. This number is currently in an abnormal opening state such as shutdown and loss reporting. It is recommended to open the number and try again.

2. The mobile phone puts the short message into the trash can, or the mobile phone security software intercepts the short message and looks for it in the short message trash can or the software has intercepted it;

3. Because there are many users, the speed of sending short messages is slow. Please try again later.

4. The mobile phone receives short messages abnormally, so try another mobile phone.

If the above reasons still can't solve the problem, please contact the local manual customer service for handling.
