BYOi, Bring your own iPhone!

BYOi, Bring your own iPhone!







As KT moved to a blacklist policy in May 2012, it is now possible for phones bought from overseas (including the iPhone 5 and Nexus 4, etc) to be used with KT services, quickly and easily.

 

Note:  Devices must support KT’s service frequencies (3G/WCDMA 2100mhz, LTE 1800mhz), must be unlocked, and not filed as a lost/stolen device.






How do I activate a device that I brought from overseas?


Depending on the way you want to use your phone, there are a few ways to activate it:


1.  I already have service with KT and want to use my current phone number with my new phone.


If you already have a phone number with KT you can switch devices by simply moving your USIM card over to your new phone.  This will allow you to use your current phone number and service with your new phone.


(In the event that your USIM card is not the correct size for your new phone,
e.g. iPhone 4 uses Micro-USIM, iPhone 5 uses nano-USIM,
you will have to stop by a kt Global Store <http://expatblog.kt.com/176> or another official kt retailer near you. to purchase a USIM of the appropriate size.)


2.  I want to sign up for a separate line of service

If you want to sign up for a second number to use with your phone, you can visit any of our kt Global Stores ( http://expatblog.kt.com/176 ) or another official kt retailer near you.



 

Please keep in mind:

 

As stated above, devices not yet released in Korea, such as the iPhone 5 or the Nexus 4, can be used simply and conveniently on KT.  However, the ability for the phone itself to connect and be compatible with Korean networks may vary from phone to phone.


The general requirements are:


· The device must support 3G/WCDMA on 2100mHz (LTE 1800mhz to use LTE data)

· The device must not be locked to a carrier (this can be verified with the retailer from which you originally purchased the phone.

· The phone must not have been reported to a carrier as lost/stolen.

· The phone cannot be a specially provisioned phone (eg. test phone, airport rental phone, etc).




Will my iPhone 5 work in Korea?


The Apple iPhone 5 is offered in 3 different model numbers worldwide, with slightly differing support for mobile carriers.  This means that some models may or may not work in Korea, due to the frequencies supported by the phone.


Below is a list of iPhone models and their compatibility with KT networks.
