Set up and use RTT on Apple Watch Ultra
Real-time text (RTT) is a protocol that transmits audio as you type text. If you have hearing or speech difficulties, Apple Watch Ultra can communicate using RTT when you’re away from your iPhone. Apple Watch Ultra uses built-in Software RTT that you configure in the Apple Watch 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., Apple Watch Ultra 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.
Turn on RTT
Open the Apple Watch app on your iPhone.
Tap My Watch, go to Accessibility > RTT, then turn on RTT.
Tap Relay Number, then enter the phone number to use for relay calls using RTT.
Turn on Send Immediately to send each character as you type. Turn off to complete messages before sending.
Start an RTT call
Open the Phone app
on your Apple Watch Ultra.Tap Contacts, then turn the Digital Crown to scroll.
Tap the contact you want to call, scroll down, then tap the RTT button.
Scribble a message, tap a reply from the list, or send an emoji.
Note: Scribble is not available in all languages.
Text appears on Apple Watch Ultra, much like a Messages conversation.
Note: You’re notified if the other person on the phone call doesn’t have RTT enabled.
Answer an RTT call
When you hear or feel the call notification, raise your wrist to see who’s calling.
Tap the Answer button, scroll down, then tap the RTT button.
Scribble a message, tap a reply from the list, or send an emoji.
Note: Scribble is not available in all languages.
Edit default replies
When you make or receive an RTT call on Apple Watch Ultra, you can send a reply with just a tap. To create additional replies of your own, follow these steps:
Open the Apple Watch app on your iPhone.
Tap My Watch, go to Accessibility > RTT, then tap Default Replies.
Tap “Add reply,” enter your reply, then tap Done.
Tip: Typically, replies end with “GA” for go ahead, which tells the other person that you’re ready for their reply.
To edit or delete existing replies, or change the order of replies, tap Edit in the Default Replies screen.
