My brother will soon be going to South Korea to teach English and he is wanting to make sure that his phone will work properly with a local carrier. The phone is SIM unlocked (we verified it with an Orange UK SIM card that I picked up last summer in England). So, does anyone know of a South Korean carrier that supports iPhones?
The iPhone 4S is from Sprint in the USA originally and they unlocked the GSM SIM slot for me because I was going to spend some time in the UK.
Will this GSM-unlocked CDMA phone work with any South Korean carriers?
