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.
