You may enroll while making a qualified T-Mobile device activation, purchase, lease or finance. If you’d like to enroll afterward, or if you’re bringing your own device, it must be within 30 days of your transaction and the device will need to pass a visual and mechanical Inspection in a T-Mobile store. Enrollment is optional, may be canceled at any time, and isn’t required to activate, purchase or finance the device or obtain T-Mobile wireless services. Please remember to make or receive a call, send a text, or access data on the device (not using Wi-Fi) to verify that your device is active on the T-Mobile network. Additionally, there are occasional "open enrollment" periods. Qualifying events apply to new customers and existing customers who are upgrading their device. Protection 360™ is not available for prepaid customers.
