ROAMING
Using the phone in a city where you do not sub-
scribe to a cellular service is referred to as
roaming
.
When you roam,
ROAMING
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 system (non-home type system).
In some areas, the cellular system’s computer auto-
matically 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 bat-
tery. (However, the roaming cellular service provider
can usually automatically determine your phone’s
ESN when you call.)
