Determining if Your Phone is Already Activated
If you purchased your phone at a Sprint Store, it is probably
activated, unlocked, and ready to use. If you received your
phone in the mail, it probably has been activated; all you
need to do is unlock it.
If your phone is not activated, please refer to the activation
card included with your phone.
Unlocking Your Phone
To unlock your phone, follow these easy steps:
1. Press the unlock button located on the lower left side
down and release to turn the phone on.
2. Select Unlock.
Note: To select a softkey, press the softkey button directly below the
softkey text that appears at the bottom left and bottom right
of your phone’s display screen. Softkey actions change
according to the screen you’re viewing and will not appear if
there is no corresponding action available.
