Textrovert by Lindsey Summers
Goodreads summary:
It’s bad enough when high-school senior Keeley grabs the wrong phone while leaving her small town’s end-of-summer fair. It’s even worse when she discovers that the phone she now has belongs to the obnoxious, self-centered Talon and that he’s just left for football camp … with her phone. Reluctantly, the two agree to forward messages for a week.
