T-Mobile IP Relay is a free internet-based telecommunications mobile app designed for iOS devices. It is specifically developed for individuals who are Deaf, Hard of Hearing, DeafBlind, or have a Speech Disability. With this app, users can make and receive relay calls and communicate using text on iOS 9 or higher, including iPad devices.

One of the key features of T-Mobile IP Relay is the ability to connect with a qualified relay operator via IP Relay. The app also offers an integrated contact list, call history, and access to live customer care. It provides a convenient and accessible way for individuals with communication disabilities to stay connected.

It is important to note that T-Mobile IP Relay is only available in the USA and US territories. International calls are either blocked or terminated. Users are required to register to use the app, and if no data plan service is selected, casual data charges may apply. While the app can be used for emergency calling, it may not function the same as traditional 911/E911 services. Users must acknowledge that T-Mobile is not responsible for any damages resulting from errors or malfunctions in accessing emergency services through IP Relay.

Overall, T-Mobile IP Relay is a valuable tool for individuals with communication disabilities, providing them with a reliable and accessible means of communication.
