Ask for the SMS prompt tone of Nokia 6 120c, "dong, dong, dong" three times. . .

Is it the voice when QQ has friends online? You can download the X file manager and find the voice in the QQ folder, and set it as SMS voice! The other easiest way is to turn on the tape recorder and say "Knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock, knock.
