Can I receive voice messages and text messages by turning off WeChat software? Turn off background running

Wechat only generates traffic when sending and receiving information, and background operations will generate tiny traffic due to message push and reminder. Voice information is actually charged according to the transmitted traffic, but the data volume of voice information is larger than that of text (short message) and consumes relatively more traffic. The traffic of voice information is 5Kb per second, which is equivalent to 5 cents.
