Turn on TTY support

Before you begin: The TTY device that you want to connect to your BlackBerry device must operate at 45.45 bits per second.

If your TTY device is designed for use with a 2.5-mm headset jack, you must use an adapter accessory to connect your TTY device to your BlackBerry device. To get an adapter accessory that Research In Motion has approved for use with your BlackBerry device, visit www.shopblackberry.com.

TTY support is designed to allow your BlackBerry device to connect with an external TTY device that converts received calls to text.
  1. Connect a TTY device to your BlackBerry device according to the instructions that came with your TTY device.
  2. In the Phone app, swipe down from the top of the screen.
  3. Tap Settings > TTY.
  4. Set the TTY switch to On.
