JoongAng Daily has an article with a summary of services from Korean mobile phone operators for the summer holidays including a ringtone to repel mosquitoes:

Female mosquitoes don’t want to be bugged by male mosquitoes during pregnancy, SKT said. According to mosquito expert Lee Dong-gyu, a professor at Koshin University, about 63 percent of mosquitoes were shooed away by the audio file. Once downloaded, the mosquito-repelling audio file can be played endlessly.

The unusual use of a cell phone is only one of many diverse services being offered by the nations’ three mobile phone operators to help people survive this scorching summer and enjoy a successful vacation.
