Girls' Generation's YoonA, f(x)'s Sulli, and EXO came together for another round of CFs for 'SKT LTE'!
 

While YoonA and Sulli get ready to go on a vacation, EXO get hyped up while playing their mobile games. The boys go more wild once they find out that they don't have to pay to play games anymore. They can just play on their 'SKT LTE' phones. Sulli also shows her 4-D personality, while YoonA excitedly grabs her suitcase to depart for a vacation made possible by playing on her phone.
