TTY support
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.
• Verify that you have inserted the TTY device connector into the headset jack on your BlackBerry® device. 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

Multiple phone numbers
About multiple phone numbers
Your BlackBerry® device might support more than one phone number, or your device might be associated with a phone number provided
by your wireless service provider and an enterprise voice phone number provided by your organization.
If you have more than one phone number associated with your device, you can switch the phone number that you use as your active phone
number. You make calls from and receive calls to your active phone number. During a call, you can use your active phone number only.
For example, you cannot place one call on hold and make a second call using another phone number.
