Understanding Roaming
Recognizing Icons on the Display Screen
Your phone’s display screen always lets you know when you’re off the
Sprint Nationwide PCS Network and whether your phone is operating
in analog or digital mode. The following chart indicates what you’ll
see depending on where you’re using your phone.
Roaming Indicator
Sprint Nationwide PCS Network
Other CDMA Digital Networks
GSM Digital Networks (International Roaming
in GSM Mode)
Tip: Remember, when you are using your phone off the Sprint Nationwide
PCS Network (in CDMA mode), always dial numbers using 11 digits
(1 + area code + number). For more information, see page 177.
Note: Unless your Service Plan includes roaming, you will pay a higher
per-minute rate for roaming calls.
Roaming on Other CDMA Digital Networks
When you’re roaming on digital networks in CDMA mode, your call
quality and security will be similar to the quality you receive when
making calls on the Sprint Nationwide PCS Network. However, you
may not be able to access certain features, such as Sprint PCS Vision.
