SK Telecom has launched its 'T Kids Phone JooN' wearable phone with accompanying rate plans. Developed in partnership with Infomark, the T Kids Phone JooN can be worn like a wristwatch or a necklace. The child wearer can make calls through the phone to up to 30 contacts preset by the parent with a touch of the phone's button.

The phone is designed to make calls with the caller's photo on the screen. Children can also receive calls from pre-selected phone numbers only.
