Why does texting consume traffic?

You change the "access method" in Settings to "Off" ————————————————————————————————————————————————— Then, turn off Settings-Notification. Turn off "Push" in the settings of communication software such as QQ and WeChat. Your SMS traffic has nothing to do with the SMS itself, but because you will receive data online in real time after you turn on "Push".

However, push is a very useful function. Personally, I suggest opening it, which won't consume a lot of traffic, but it is very convenient to inform you of the new emails and QQ information you receive in real time. You will know how useful it is after using it.
