What Is RTT on iPhone?

As the name suggests, RTT (Real-Time Text) is a feature that allows you to make and receive calls on your iPhone using text. It’s an accessibility feature aimed at helping hard-of-hearing individuals or those with speech difficulties.

With the feature, you get to see responses in text formatting in real time. You don’t have to wait until they’ve typed their message and hit Send to see the message. The same is true on your end.

If you don’t use the feature currently, you can turn it off so you don’t see the option in your iPhone’s calling menu. Later, you can turn it back on should you need it.

How to Turn Off RTT on iPhone

To turn off RTT calling, first, launch Settings on your iPhone. Then, head into “Accessibility” or General > Accessibility, depending on your iOS version.

Select the "Accessibility" option.

In the “Accessibility” menu, tap “RTT/TTY” or “RTT/Textphone.”

Select "RTT/Textphone."

On the following page, toggle off both “Software RTT/TTY” and “Hardware RTT/TTY” or “Software RTT/Textphone” and “Hardware Textphone.”

Tip: To reactivate the feature in the future, simply turn on both options.

Toggle off options to turn off RTT on the iPhone.

And that’s it. You’ve now disabled the RTT calling feature on your Apple iPhone.

Want to make your incoming iPhone calls fullscreen? If so, there’s a way to do just that.
