Real-time text (RTT) is a protocol that transmits audio as you type text. If you have hearing or speech difficulties, AppleWatch with cellular can communicate using RTT when you’re away from your iPhone. AppleWatch uses built-in Software RTT that you configure in the AppleWatch app—it requires no additional devices.
Important: RTT is not supported by all carriers or in all regions. When making an emergency call in the U.S., AppleWatch sends special characters or tones to alert the operator. The operator’s ability to receive or respond to these tones can vary depending on your location. Apple doesn’t guarantee that the operator will be able to receive or respond to an RTT call.
