In some regions, you can make emergency calls from HTC Wildfire S even if you don’t have a SIM card installed or your SIM card has been blocked.
On the Home screen, tap Phone.
Dial the international emergency number for your locale (for example, 000), and then tap Call.
Note: Additional emergency numbers may be included in your SIM card. Contact your mobile operator for details.
If you’ve enabled but forgotten your lock screen password, lock pattern, and/or the SIM lock, you can still make emergency calls by tapping Emergency call on the screen.
