About TTY support
When you turn on TTY support and you connect your BlackBerry® device to a TTY device, you can make calls to and receive calls from TTY
devices. Your BlackBerry device is designed to convert received calls to text that you can read on your TTY device.
Prerequisites: TTY support
• Verify that your wireless service provider supports this feature.
• Verify that your TTY device operates at 45.45 bits per second.

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
