Overview

  • All four major German carriers activated Real-Time Text on June 28 to comply with the European Accessibility Act deadline.
  • RTT transmits each keystroke and symbol during a voice call in real time, consuming no mobile data and incurring only standard call charges.
  • Users can enable RTT directly in their phone’s accessibility settings or switch to it during a call without installing extra apps or changing contracts.
  • Android devices require manufacturer updates to fully support RTT while iPhones running iOS 18.5 and above are already compatible with Android 10+ and iOS 11.2+.
  • A silent-text emergency feature using RTT for discreet communication with police via numbers 110 and 112 is scheduled to launch in summer 2027.
