Recently, my mobile phone always receives short messages online, but there is no number. Give me a link address, let me play games, watch videos, etc ... It's so annoying ... why not?

This kind of short message is usually an advertising game or something. You can delete it directly and don't open it. If there is a setting for refusing to receive in the mobile phone, you can set a blacklist, or you can only receive short messages with numbers stored in the phone book. In this way, you can reduce spam messages and save a lot of power for your mobile phone.
