Really enjoying Seoul so far. It is very hard to make friends at first as not many people will speak English or are too afraid to. Maybe easier in Itaewon. For phone service I was able to get month to month service on KT with unlimited data for only 35,000 won a month. Check out the desk with a sign in Thai on the electronics floor at IPark Mall connected to Yonsan station for this deal. They speak great English as well.
