how to use the Nokia Lumia 521 in a South Korea cellphone network?

Since February 2014 i have sim-unlocked my lumia 521 & was able to use it in the philippines Globe network from march 'till june.
now i'm in south korea for a 2 year teaching contract & have not successfully been able to have any of the cell network providers get the 521 to work with their service.
a fellow teacher mentioned that it may be due to the fact i need to do a device-unlock beside the sim-unlocked i've already done.

thank you in advance for your assistance regarding this matter,

GSM network: 850 MHz, 900 MHz, 1800 MHz, 1900 MHz.
WCDMA network: 850 MHz, 1700 - 2100 MHz, 1900 MHz.
