The SMS port is occupied ... what should I do ... I understand.

Hello, I'm glad to answer your question.

This situation is mostly caused by installing two or more similar softwares.

It is also possible that similar software has not been deleted.

See if your mobile phone is also equipped with 360 mobile guards, security butlers and other security software.

This kind of software can only be loaded with one, and that's what happens when you install two. If two are installed, delete one.

If there is only one, we will restore the factory settings.

I am in a good mood on Sunday.
