"Smartphones and tablets are our most personal devices, and as consumers store more information on them, there’s an elevated interest to protect them. Lookout is a great fit for T-Mobile because the app is powerful yet easy to use, and it gives our customers protection across a range of mobile security threats."-Torrie Dorrell, vice president, T-Mobile USA
Lookout founder and CEO John Hering is happy about his firm's partnership with the carrier. "T-Mobile is a leader in mobile communications, and we’re thrilled to work together on enhancing mobile security. Having the Lookout app preloaded on T-Mobile devices means customers can quickly and easily access content that helps them feel safe and confident to do more with their phones."
