Why can't my Unicom Bili mobile phone receive SMS verification code?

There may be the following reasons for not receiving the verification code:

1. software conflicts, and some software firewalls or protection functions will also block some sent information accordingly;

2. You can change the machine or card to see if it is a hardware factor;

3. Check whether the mailbox is full first. If it is full, please delete some information.

You can try to test whether it can be received in other places and see if it is the reason for the weak local signal.

5. Check whether your number is currently in an abnormal state such as arrears of downtime and loss reporting;

6. Your mobile phone may have put the short message in the trash can. You can check it in the short message trash can first.
