By using the IP Relay app for emergency calling you agree that T-Mobile is not responsible for any damages resulting from errors, defects, malfunctions, interruptions, or failures in accessing or attempting to access emergency services through IP Relay whether caused by the negligence of T-Mobile or otherwise.
