“Aaaaaaaah, so amazing~” You have likely heard this phrase on social media at least once these days. It is the new 2026 advertising campaign released by SK Telecom’s T Roaming, featuring actor Ji Chang-wook as its model.
As soon as the ad was released, it garnered intense attention as “Ji Chang-wook’s epic transformation.” This is because he, who usually maintains a gentle and stylish image, delivered a comical performance while screaming at the top of his lungs. This humorous approach, which breaks conventional advertising conventions, is spreading like a meme among the MZ generation and gaining immense popularity.

SK Telecom is Korea’s leading telecommunications company, and T Roaming provides international roaming services for overseas travelers. This advertisement promotes T Roaming’s new service, “Azu,” emphasizing easy and amazing benefits.
The selection of Ji Chang-wook as the model appears to be a strategy to maximize the “twist” effect. It was determined that the "surprise" of the T Roaming Service could be conveyed most intensely by having a top actor shed his image and "ruin" his image. This is a fresh attempt to break the mold of traditional telecommunications advertisements, which are usually serious and static.
3️⃣ Star’s Influence
Ji Chang-wook is a global star who possesses a strong fandom not only in Korea but across Asia, thanks to numerous works such as the dramas *Healer*, *Suspicious Partner*, and *Welcome to Samdalli*.
