120 Section 2D: Controlling Your Roaming Experience
Understanding Roaming
Recognizing the Roaming Icon on the Display Screens
Your Main LCD screen always lets you know when you’re off
the Sprint National Network. Whenever you are roaming, the
phone displays the roaming icon ( ).
Roaming on Other Digital Networks
When you’re roaming on digital networks, your call quality
and security will be similar to the quality you receive when
making calls on the Sprint National Network. However, you
may not be able to access certain features, such as Sprint
Power Vision.
Tip: Remember, when you are using your phone off the Sprint
National Network, always dial numbers using
11 digits (1 + area code + number).
Note: Unless your Sprint service plan includes roaming, you will pay
a higher per-minute rate for roaming calls.
Note: If you’re on a call when you leave the Sprint National Network
and enter an area where roaming is available, your call is
dropped. If your call is dropped in an area where you think
Sprint service is available, turn your phone off and on again to
reconnect to the network.
