The latest move in this regard appears to be the company closing a loophole that allowed in-store customers to sidestep its app. Until recently, paying with cash meant transactions could still be handled through older in-store systems rather than the app, but that no longer seems to be the case.According to reporting from PhoneArena, T-Mobile has now added cash payments directly into T-Life, meaning those transactions are also routed through the app. The change was highlighted in a Reddit post and subsequently confirmed to the publication by a T-Mobile employee, suggesting the update is already live in stores.
