Assigning a PIN to help protect the nano SIM

card

You can help to protect the nano SIM card by assigning a PIN (personal identification
number) that you enter before accessing the nano SIM.

Make sure you have the default PIN of the nano SIM card from your mobile
operator before continuing.

1. Go to Settings, and then tap Security.

2. Tap Set up SIM card lock, then select Lock SIM card.

3. Enter the default PIN of the nano SIM card, and then tap OK.

4. To change the nano SIM card PIN, tap Change SIM PIN.

Restoring a nano SIM card that has been locked out

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

You need a PUK code to restore access to HTC One. Contact your mobile operator for
this code.

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.

Disabling an app

Apps, even if not used often, may be running in the background and downloading
data. If an app cannot be uninstalled, you can disable it.

1. Go to Settings, and then tap Apps.

2. Swipe to the All tab.

3. Tap the app, and then tap Disable.
