My Sprint is a mobile application that lets you manage your Sprint plan on-the-go. It's free, easy to use, and its features will help you to avoiding making trips to a store. The My Sprint app is versatile and allows you to view your mobile usage (i.e. texts, calls, and data), check your upgrade eligibility, manage your plan, view and pay your Sprint bill, and search for technical advice. If you're using a family plan, it will also give you a simple way to manage all of the devices on your plan.
My Sprint for iPhone is also available on Android.
