Band stuck in an elevator music video...they have cell fones and it has to do with heartbreak i think. Guy that looks like Joe Jonas is a red robe fancy hotel room...3 member band?

The music video you're describing sounds a lot like the Jonas Brothers' "Sucker" music video. The video features the Jonas Brothers, including a guy that looks like Joe Jonas, dressed in red robes and performing in a fancy hotel room. The video also involves the use of cell phones and themes of heartbreak.
