To get rid of the TTY symbol, you'll need to access the settings menu on your device. Depending on the type of device you have, this may be done differently. Generally, you'll either need to go into your device's settings or press a certain key combination. From there, navigate to the Accessibility or Phone settings and look for an option to toggle off TTY mode. Once it is disabled, save your changes and restart your device - that should do the trick! If not, contact your provider or manufacturer for further support as they will be able to provide specific steps and advice tailored to your specific model.
