RTT, or real-time text, is an accessibility feature that’s built into all iPhones running iOS 10 or later.[1] It allows you to communicate using text during a phone call—without having to use an external TTY device. If you want to turn RTT off, you can do it easily in your iPhone’s Settings menu. We’ll also explain how to troubleshoot if you’re still seeing RTT with your calls, plus how to change individual settings in the RTT menu.
Things You Should Know
- Turn off RTT on your iPhone by going to Settings > Accessibility > RTT/TTY and toggling off Software RTT.
- If you still see RTT on your calls even after you’ve turned it off, you may need to reset your iPhone’s settings to default.
- You can adjust individual settings, like whether you answer calls as RTT by default, in the RTT/TTY menu.
Steps
Turning Off RTT
OpenSettings on your iPhone. It’s easy to turn off RTT in Settings on your iPhone. To get started, launch the Settings app from your Home Screen or App Library.
Tap Accessibility. Scroll down until you find Accessibility in the settings menu, then tap on it.
Scroll down and tap RTT/TTY. It’s located in the Hearing group, near the bottom of the Accessibility menu.
Toggle off theswitch next to Software RTT. If the toggle switch next to Software RTT is in the On position, tap it to turn RTT off. The switch should turn gray.
- If you also want to disable hardware TTY, which allows you to make calls with an external teletypewriter device, toggle off Hardware TTY in the same menu.

Troubleshooting
Make sure the other caller has RTT turned off. Some users report having RTT interrupt their voice calls even if it’s turned off in Settings. This can happen if the person you’re talking to has RTT activated on their phone, even if you don’t. Ask the other person if RTT is enabled on their phone, and talk them through how to turn it off.
Reset your iPhone’s settings if you can’t get it to turn off. Sometimes RTT will continue to run during calls even if you’ve switched it off. Once you verify that the person you’re talking to doesn’t have it enabled on their phone, try resetting your phone’s settings and see if that fixes the issue. To do it:[2]- Open Settings, then tap General.
- Select Transfer or Reset iPhone.
- Select Reset All Settings. You may be prompted to enter your passcode. This will return all your iPhone’s settings to their defaults. You shouldn’t lose any apps, media, or data, but you might want to back up your phone first just in case.
