ROAMING
In some areas, the cellular system’s computer automatically
recognizes roaming telephones. In other areas, you must
contact the service provider before it can recognize your
phone. The operator needs to know your telephone number,
your phone’s ESN (Electronic Serial Number), and how you
plan to pay for your calls. There is normally an additional
charge for roaming calls.
Note: Your phone’s ESN is under the phone’s battery; how-
ever, the roaming cellular service provider can usually auto-
matically determine your phone’s ESN when you call.
When you roam, RM flashes slowly on the display when the
phone is using a home-type cellular system. The indicator
flashes rapidly when the phone is using a cellular system that
is different from your home system.
USING CELLULAR SYSTEM
PIN DIALING
Your cellular carrier might require that you use a personal
identification number (PIN) when you make calls. This num-
ber assures the cellular system that the person placing the
call is an authorized user.
Contact your cellular service provider to determine if a PIN is
required and obtain the PIN (seven digits or less) to place
calls through the cellular system you subscribe to. If a PIN is
required, follow the steps in “Storing Speed Dial Numbers” on
Page 31 to store your PIN in memory 07, then follow the
steps in “Enabling/Disabling PIN Dialing” on Page 50 to en-
able PIN dialing on your phone.
