Huawei mate7 automatically and regularly sends messages to China Mobile and China Unicom. Do you want to format it all at once or send it automatically?

If the SMS sent to China Unicom and China Mobile is a traffic inquiry SMS, it is usually your mobile phone system or installed traffic monitoring software (such as 360 Mobile Guardian and Tencent Mobile Manager). ) is automatically sending instructions to correct traffic conditions. For example, Huawei Mate7 system has its own traffic monitoring. According to this post, you can see if it is in line with your situation. If the automatic flow calibration function is turned off in the system, you won't send text messages. Or you can turn off this function by opening the settings of the traffic monitoring software on your mobile phone and turning off the automatic sending instruction to correct the traffic, so that you won't send this kind of short message. If not, I suggest you contact the mobile phone manufacturer for more help.
