Mobile phones will always automatically download and install applications such as fine novels and persistent games for no reason.

If it is a smart phone, even if someone sends you a text message, you have to download your own pictures and news, especially pictures, at least 200 KB. . You didn't turn off the traffic, so when you download the pictures and news attached to the SMS, you will automatically download the traffic. As for the inexplicably downloaded software, it may be that when you look at other software, you will automatically download it by clicking on the advertisement at the bottom of the corner. . . . I saw it several times, and I didn't know it until he asked me to pretend. . . .

No traffic, just call to turn it off, even if he wants to download. . . .

Be careful of advertisements. When you open the software, you are staring at the download bar. If you have a download program, you don't want to turn it off directly. . .

If you really recite to that extent and your number is stolen, buy a new card. Not much money. . .

If it is machine card binding, take it to the place where you bought the mobile phone and let the salesperson have a look. . .

Instructions! ! It's definitely up to me. I'm exhausted. Please adopt it.
