local carriers. Contact the office of your home cellular phone
company for information about the roaming agreements they
have with other cellular phone companies. In some areas,
roaming telephones are automatically recognized by the
cellular system’s computer. In other areas, you must contact
the cellular phone operator before it can recognize your
phone. The company needs to know your telephone number,
your phone ESN (electronic serial number), and how you
plan to pay for your calls. There is usually an additional
charge for roaming calls.
Note: The ESN for your phone is located in the battery
compartment of the phone, and is comprised of the first
8 digits preceded by NEC’s company code of 189.
