btw ,I am confirmed and will be going to Daegu city this coming 14th July.

But I am a bit blur on the following, and hope you could clear my doubts:

1) As my exchange program will be based in Daegu , South Korea, I have decided to have a trip beyond this city, maybe at Busan, Seoul etc which have a lots of interesting and tourist hotspot places to travel right after my exchange program. and so I have extend my flight to 2 more days for travelling around to these places. which places do you think are worth to visit and have plenty of cheap motels to rent for staying up to 2 days?

2) How is the mobile phone up there? is there a need to buy a new sim korean number? I am using Digi btw.which do you think more affordable?

3)Besides Jeju island as a must visit places in south korea, what else places are recomended highly?

I don't speak Mandarin, Cantonese or Korean and yet I survived during my 9 days trip in Korea. No worrylah, if you do your homework, you will able to navigate your way in the city. No need to join tour group. Waste of money and time.
