Your phone as a network device
Your telephone requires a service provider in order to send and receive calls.
Your phone is only one part of a system or “network” of devices, that makes it
possible to send and receive calls, text messages, voice message, access the
Internet using the MiniBrowser, and to take advantage of all of the other
services and features provided to you and your phone.
Your phone will always try your call using your home system, but if this is
unavailable, then the phone will use the preferred roaming system.
If you cannot roam, your call will not be connected, and in some service areas,
an operator may ask you how you would like to pay for the call.
To make all of the features available to you, your phone is designed by
Samsung and your service provider to allow your service provider to send (at
any time) a variety or information and messages to your phone. You may think
of this as an over the air service to your phone. During an over-the-air
programming session, your phone may display the following messages:
• “Programming in progress...” - this message means the phone is
downloading data. Do not turn your phone off while this is occurring.
See the CAUTION: below.
• “Programming successful!...” - if this message displays after a series
of other messages, then it means that your phone has been successfully
reprogrammed. You can now continue to use your phone as you
normally do.
• “Programming unsuccessful!” - if this message appears contact your
service provider.
CAUTION: If you turn off your phone during a programming session, your
phone (or some features) may not work properly in the network. If this
happens don’t worry, contact your service provider for help in correcting the
problem.
