[솔나무]

I have  learning  cellphone operating at administrative wellfare office .

We can operate  ordaniary something like sns,calling etc

But cellphone is used by graphic,cafe,etc

Last week I learned about emergency call, urgency call.

Emergecy call is sos and It means calling by mine  urgently,

But emergency contact number  means  for calling by another people in your black out.

Sos caliing is used to call by 5  touch your phone side button  in case that you can't call like your drop by disease, 

Urgent call is also that when another pepole  call your relative by your black out.

and so we must  set up our family phone number with emergency contact number.
