Why does Unicom mobile phone send text messages to check traffic?

I suggest you check whether there is any traffic monitoring software in your mobile phone, such as 360 mobile phone security guard and Tencent mobile phone housekeeper. If there is such software, the software vendor will send traffic query messages to 100 10 periodically to keep the accuracy of its traffic statistics. If not, you can uninstall this kind of software. Half-year traffic is not cleared across months and is valid for half a year. Click /sAAGm to enjoy a 20% discount!
