The mobile phone always receives some useless mass messages inexplicably, which is very annoying!

It's best to turn off the data, this kind of push information is a waste of traffic. This is what you will bring in some downloaded software, which is basically advertising and the like. The simple way to organize this kind of thing is to intercept it with 9 1 assistant. It used to be blocked one by one, but it was very laborious. After using 9 1 assistant, it was much better. I hope I can help you.
