ROAMING
Using the phone in a city where you do not sub- scribe to a cellular service is referred to as roam- ing. When you roam, ROAM turns on steadily if the phone is using its home type system, and flashes when it is using a cellular system that is different from your home type system
In some areas, the cellular system’s computer au- tomatically recognizes roaming telephones. In oth- er 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 bat- tery. (However, the roaming cellular service provid- ers can usually automatically determine your phone’s ESN when you call.)
