Switch between your work phone line and personal phone line
Some companies and organizations support two phone lines: one for personal use and one for work use. You can make
calls using different phone numbers, allowing you and your organization to distinguish between personal use and work use
of your device. You can also view recent calls for each phone line, and see which phone line is being called when you
receive an incoming call.
In the Phone app, tap
Tap Change Phone Line.
