<b>It's a calling card issued from Korea. If you know someone there, stationed there, etc.... PICK UP. If not, don't ... (unless you know someone in Wyoming .. 307 area code).</b>
i'm in the army stationed in korea and when i use a calling card to call my parents from my cell phone (or anyone else with caller id), it always shows up as "rodney trees" on their caller id. if you have a friend or family stationed in korea, pick up. it could be them calling you. also, if they're calling really early in the morning (2am for example), it could be a normal time for them (afternoon) due to the time difference, and maybe they just forgot to do the math.
hope this helps.
