I'm interested in the time limited samsung.com promotion, "buy one, get one for t mobile". Because I usually visit Korea for business, I hope to use this promotion phone in S. Korea. I wonder whether this phone is a country-lock status. Is it possible to unlock the country lock of this phone for using in S. Korea? To whom do I ask to unlock this phone?
If they are the TMobile variant, it would be locked. Phones aren't locked to a country but rather a carrier. So you would need to be a T-Mobile customer to get it unlocked. I would first start by checking what the Korean signal bands are for your carrier and see if the model phone you are purchasing supports them or not. Also then consider if you would be able to meet the requirements to get it unlocked by TMobile.
