About Purchasing How do I find out if my phone is unlocked ?

In order to use Korean simcard in Korea, device should be unlocked. You can check it through your current mobile carrier in your country before you come to Korea.

Whereas a locked cell phone will only accept SIM cards from its current provider, an unlocked cell phone will accept a SIM card from any service provider. (This is very useful if you want to use your phone abroad, for example.) To identify an unlocked cell phone, follow these steps.

Step 1

Turn off your cell phone, remove the battery cover and battery, then look for the SIM card.

1)  If you cannot find a SIM card in the back, look for one in the side or top of the phone. It may be covered by a small plastic flap. On some models, you will need to open the flap with a pin.

2) If your cell phone operates without a SIM card, it is a CDMA (Code-Division Multiple Access) phone, as opposed to the more common GSM (Global System for Mobile communication). CDMAs cannot be unlocked.

Step 2

Insert a different service provider's SIM card into your phone and close it back up. For example, if you have T Mobile, insert a Cingular SIM card. The easiest way to do this is to borrow a phone from a friend.

Step 3

Turn on your phone.

Step 4

Try to access the phone book or make a call. If the phone functions normally, you have an unlocked cell phone. If it says “Restricted,” “Contact Service Provider,” etc. (in other words , doesn’t allow you to access your phone book or make calls), you have a locked phone that won’t accept other SIM cards from other providers.
