Switching Between Phone Numbers
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:
In most areas, there are two competing cellular carriers, the 
“wireline” carrier and the “non-wireline” carrier: If your 
cellular service is from a:
• non-wireline carrier—the display will indicate that 
your home system is system A
• wireline carrier—the display will indicate that your 
home system is system B
