Getting Started With Sprint PCS Service
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 to turn the phone on.
2. Press Unlock ( ).
3. Enter your four-digit lock code. (For security purposes,
the code is not visible as you type.)
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.
Tip: If you can’t recall your lock code, try using the last four digits
of either your Social Security number or wireless phone
number or try 0000 or NATL (6285). If none of these work, call
Sprint Customer Service at 1-888-211-4PCS (4727).
