10086 keeps sending text messages to remind me that the traffic has run out. But I'm useless. There will be no traffic after noon today. Always connected to the wireless, at night 1

When you connect to the wireless, your main data exchange is through wifi, but a few of them are through the mobile data traffic of your mobile phone, so you should manually disconnect the data traffic when connecting to WiFi in the future. I suggest you download a 360 mobile phone guard for your mobile phone. Your traffic is a little too much. Check for malware.
