What is the Mosquito Ringtone?
The short version is a tone outside the audible range of hearing of most people over 30.  This means that you can get phone calls and receive text messages in class or school without teachers hearing it.

You should use the last tone on this list that you can hear.  For instance, if you can hear both the 18.8khz and the 19.8khz tone, use the 19.8khz as less people will be able to hear it.  You can download it at the above source.
