SMS, one of the mobile phone functions, has been recognized as useful mean for public warming in rural areas. However, there are little research have been conducted to clarify an actual effect of the SMS. This paper visualizes a result of the demonstration experiment which sent SMS to people who live in a rural mountainous area. The result clarifies that SMS can reach the area where a loudspeaker, current warning mean in the area, cannot reach when its sound is bothered by rain. Additional analysis including visualization of the SMS penetration in chronological order is required for further understanding on the SMS in warning.
