Setting up app links

If there's more than one app that can be opened when you tap a link—such as a shared social post or
media link—you may be prompted to choose the app you want to use. When you're prompted after
you've tapped a link, select an app, and then tap Always to set that app as the default app to use.
You can also go to Settings to see how app links have been set up for different apps and change them.
1. From the Home screen, tap
2. Tap Apps.
3. Tap > Configure apps > App links.
4. Tap the app you want to configure, and then tap Open supported links.
5. Select Open in this app to always open the app without being prompted when you tap a link.
You can also choose whether to always be prompted to choose the app or never use the app
for opening links.

Assigning a PIN to a nano SIM card

You can help to protect the nano SIM card by assigning a Personal Identification Number (PIN).
Make sure you have the default PIN provided by your mobile operator before continuing.
1. From the Home screen, tap
2. Tap Set up SIM card lock.
3. Choose to lock the card, enter the default PIN of the card, and then tap OK.
4. To change the 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 card
will become "PUK-locked."
You need a Pin Unlock Key (PUK) code to restore access to HTC One M9. 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.
