Nextel i920 User Manual

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 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.

e

key command displays Unlock.

Note: You can still receive calls and make emergency calls when the keypad is 

locked.
