Switching between phone lines

Your phone can have two service accounts, or phone lines, associated with
it. Each phone line has its own phone number. When you are using one
line, you cannot receive calls from the other.
It would be as if the phone were “off” for that number. Your voicemail,
however, will still take messages. All contacts and settings are shared for
both lines.
Note: Before you can switch between phone lines, you must first establish a
second phone line with your service provider. Once it has been
established, a second phone number becomes available in the menu
for selection.
1. Select Menu → Settings → Network → Set Phone Line.
2. Select the other line and press .
