  2. Do the following:
    • For your CDMA card, tap Set up UIM card lock, and then select Lock UIM card.

Restoring a UIM or SIM card that has been locked out

  1. On the Phone dialer screen, enter the PUK code, and then tap Next.
  2. Enter the new PIN you want to use, and then tap Next.
  3. Enter the new PIN again, and then tap OK.
