I logged into the mobile phone business hall of China Unicom, but I couldn't get the verification code. What happened?

You can try logging in again in the following ways:

1. Restart your Unicom phone or try to replace it to see if it recovers;

2. If you still can't receive the verification code normally, you can ask the nearby Unicom users whether they can receive the short message normally.

You can contact the customer service of Unicom to inquire the address where you sent the message. Is it possible that the maintenance or construction of the base station caused the signal to be unstable and could not be received?

4. Check whether other short messages on the mobile phone can be received normally;

If you still can't receive it normally after checking the above situation, you can call Unicom's customer service hotline 100 10 for detailed verification.
