Sprint Nextel S720 - Manual (Page 59)

Section 2C: Menu Options 53
ⅷ 1xRTT Only: Select the 1xRTT Only option if you would like to
have Sprint PCS Connection Manager connect to only 1xRTT
networks. When you apply this option, the next time you make
a connection Sprint PCS Connection Manager will search for
only 1xRTT networks.
Applying your Mode Preference
1. Click OK or Apply on the Settings dialog box to reset your
modem. When you apply your service preference the
following dialog will appear: “Service setting was changed
successfully. Please wait while the modem is reset for the
changes to take effect.”
2. Click OK to close the dialog box. When the modem is reset
the Go button will be visible and the Connection Manager
User Interface will display “Disconnected.” This may take a
moment.
Roaming Preference
The Roaming section is used to change your roaming preference.
Your coverage area and billing charges depend upon your service
and the type of account you have. There may be surcharges for
roaming service that vary based on whether you are in a preferred
roaming area or a non-preferred roaming area. If there is no
roaming agreement between Sprint and the local carrier, you may
be unable to complete calls in a non-preferred zone.
Note: Sprint PCS Connection Manager will always try to connect to
a Sprint CDMA 1xEV-DO network first before attempting to
connect to an 1xRTT network. 1xEV-DO networks always
have priority! If an 1xEV-DO network is unavailable then
Sprint PCS Connection Manager will search for an available
1xRTT network.
Tip: If the signal strength is too weak and you are unable to
connect using 1xRTT in the 1900 MHz frequency, or if your
connection fails due to this selection, disable the setting.
