Make a phone call?



I'm trying to call PNU from my cell phone and because I'm terribly smart it's not working so please help, haha. The number is 82-51-510-xxxx. I know that 82 is the country code and that 51 is busan's city code but still can't make a call however many variations I've made. My cell starts with 010 so please clear this up for me, thanks!

Where are you calling from?

Where are you calling from? If you are calling from inside Korea there is obviously no need for the country code and you should just call  051-510-xxxx
