App Description

31X South Korea is designed to help members of the U.S. Military community in South Korea more conveniently dial Defense Switch Network (DSN) numbers from their cellphones or non-DSN landlines. Simply dial the DSN numbers (don't forget the 315) then click on the phone icon to dial, or the clipboard to share it.

Most DSN numbers have a direct commercial conversion (i.e., 315-755-XXXX = +82 0503-355-XXXX). The app uses the first 6 digits of the DSN number to retrieve the corresponding local number "prefix" from its internal database and appends the last 4 digits of the DSN number to complete the phone number.

Thank you for using 31X South Korea. We hope you find it convenient.
