Change Your Phone Number
Your phone can operate on two different home systems. If
you travel often, you can have your phone programmed with
two cellular numbers to reduce roaming. This feature allows
you to change your active number to the one appropriate for
the area you're in.
When your phone has two numbers, both are designated as
your home system but only one number can be active at any
given time. Calls are placed and received by the currently
active number only. Each time you turn your phone ON,
you'll see a message in the display that indicates which phone
number and home system are currently active:
Non-wireline type with phone number 1
Non-wireline type with phone number 2
Wireline with phone number 1
Wireline with phone number 2
In most areas, there are two competing cellular carriers, the
"wireline" carrier and the "non-wireline" carrier. If your
cellular service is from the non-wireline carrier, the display
will indicate that your home system is system A. If your
cellular service is from the wireline carrier, the display will
indicate that your home system is system B.
