Why is there only one person who can't receive text messages and there is no blacklist?

1, you can try to send yourself a short message to see if you can receive it;

2. If you can receive other people's short messages normally, but only one person can't receive them normally, it may be that there is something wrong with the other party's mobile phone, and whether the other party sent them successfully; Whether the other party's mobile phone is on the blacklist;

3. There is no blacklist, so if there is a function similar to a firewall, you can uninstall these softwares first.

4. You can change a sim card to see if there is a problem with the sim card;

5. If it still doesn't work, you can back up the data and try to restore the factory settings to see if it can be solved.

6. If it still doesn't work, it's time to visit the site.
