Why does the mobile phone have to be turned off and turned on to receive information?

Newly bought mobile phone, I suggest you use it again.

Because many softwares are pre-installed, these softwares may lead to unstable functions of other softwares installed in the mobile phone.

But in this case, you can try to stop the service or incoming call of 360 security guards, and then try to see if you can receive SMS normally.

Excuse me, should I intercept or need to turn it off to receive the information received normally?

Or I suggest you give it to me directly, and we'll communicate online first.
