The reality mogul revealed the spot Monday on Conan with Conan O’Brien.
“The ad really incorporated a lot of my personality,” Kardashian West tells PEOPLE. “We really went over scene by scene and what selfies I thought would really showcase me and what I would do,” she explains. “I ski, I went to tennis camp growing up. So there are some things in the commercial that I don’t think people know about me.”
But it’s not the first time Kardashian West has appeared in a Super Bowl ad – she did one for Sketchers in 2011.
“I think it’s such an iconic time, everyone watches the Super Bowl,” she says. “We wanted to come up with something that was fun, witty, sexy and I think this commercial really kind of has everything,” she says of the comedic T-Mobile ad.
“Whether it’s business calls, selfies, whatever, I’m always on my phone,” says the star, 34. “And the concept was just so fun and I just got it right away, it clicked.”
