Nokia 5700 cancels SMS tone.

Enter the main page, press the Mi key to enter the personalized menu, select the theme mode, and then enter the audio theme. There is an information-related item here. When I went in, I found that the message had been sent, so I changed the ringtone to mute. If not, download an x-plore from Saipan Forum and delete the two ringtones that come with the mobile phone.
