Protecting your SIM card with a PIN

Add another layer of security for HTC Jetstream by assigning a PIN (personal identification number) to your SIM.

Make sure you have the default SIM PIN provided by AT&T before continuing.
  1. From the Home screen, tap > Settings.
  2. Tap Security > Set up SIM card lock, then select Lock SIM card.
  3. Enter the default SIM card PIN, and then tap OK.
  4. To change the SIM card PIN, tap Change SIM PIN.

Restoring a locked SIM card

If you enter the wrong PIN more times than the maximum number of attempts allowed, your SIM card will become ​“‍PUK-locked.”

You need a PUK code to restore access to HTC Jetstream. This code may have been provided by AT&T when you received your SIM card.
  1. On the keypad 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.
