The Basics
Using a Different SIM Card in Your Smartphone or Using Your SIM
Card in a Different Phone — Information May Be Lost
If you want to use a SIM card other than the one that is in your Smartphone, please
contact Sprint Customer Care to verify that the SIM card you want to use is compatible
with your Smartphone.
The SIM card that comes with your Smartphone is designed for optimal Contacts storage
and feature use.
If you remove your SIM card and use it with another phone, or use another SIM card with
your Smartphone, the following information is erased from your Smartphone:
• The recent calls list
• The call alert queue
• Call forwarding settings
• Call waiting settings
• Owner information
Note: In some cases, Contacts may not be accessible if you move your SIM card to
another phone. Contacts entries created with your Smartphone may not
readable be by an older iDEN SIM-based phone or may appear differently than
on your Smartphone.
Locking the Keypad
• Locking the keypad turns off keypad functionality. This is a helpful feature if, for
example, the Smartphone is turned on and in your pocket, and you want to prevent
accidental keypresses.
Lock the keypad
• On the Home screen, press and hold e. When the Smartphone is locked, the left soft
key command displays Unlock.
Unlock the keypad
• On the Home screen, select Unlock and press #.
Note: You can still receive calls and make emergency calls when the keypad is
locked.
