How to set the number of SMS information center to be empty?

SMS-SMS Settings-Mode Settings-Then there are four modes to choose from (is there only one mode for your mobile phone? ). The first mode is the default SMS mode, regardless of it; The other three initial states are all empty. Just select one and right-click to finish.

I wonder what kind of mobile phone the landlord has and whether the method is the same.

I used to choose the empty center number when I played games, and just call me back when I sent a text message. I don't need to change it. I hope I can help you. ^_^
