About multiple phone numbers
Your SIM card might support more than one phone number, or your BlackBerry® 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 can receive calls to all phone numbers that are associated with your device, but you make calls using 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.
Switch the active phone number
1. In the phone options, click General Options.
2. Change the Active Line field.
3. Press the Menu key.
4. Click Save.
