Making Sure You're Secure when Using Trusted Devices
Different Bluetooth® devices support different Bluetooth® standards and security
capabilities. There's a chance someone could keep your Xperia™ device unlocked
by imitating your Bluetooth® connection, even if your trusted device is no longer
nearby. Your device is not always able to determine whether your connection is
secure from someone trying to imitate it.
When your device can't determine whether you're using a secure connection, you'll
get a notification on your Xperia™ device and may need to manually unlock it
before the trusted device can keep it unlocked.
Bluetooth® connectivity range can vary depending on factors like the model of your
device, the connected Bluetooth® device, and your environment. Depending on
these factors, Bluetooth® connections can work over distances up to 100 meters.
Connecting to Trusted Places
When the Trusted places feature is set up, the lockscreen security on your Xperia™
device gets disabled when you are in a designated trusted location. For this feature
to work, you must have an internet connection (preferably over Wi-Fi) and allow
your device to use your current location.
To set up trusted places, first make sure high-accuracy location mode or battery-
saving location mode is enabled on your device before you add home or custom
locations.
The exact dimensions of a trusted location are an estimate and may extend beyond
the physical walls of your home or other areas you have added as trusted locations.
This feature can keep your device unlocked within a radius of up to 80 meters. Also
be aware that location signals can be replicated or manipulated. Someone with
access to specialized equipment could unlock your device.
SIM Card Protection
You can lock and unlock each SIM card that you use in your device with a PIN
(Personal Identification Number). When a SIM card is locked, the subscription
linked to the card is protected against misuse, meaning you have to enter a PIN
every time you start your device.
If you enter the PIN incorrectly too many times, your SIM card will get blocked. You
then need to enter your PUK (Personal Unblocking Key) and a new PIN. Your PIN
and PUK are supplied by your service provider.
To Set Up a SIM Card Lock
1 From the Homescreen, tap
.
2 Find and tap Settings > Security > Set up SIM card lock.
3 Tap the Lock SIM card slider to enable or disable the SIM card lock.
4 Enter the SIM card PIN and tap OK. The SIM card lock is now active and you will
be prompted to enter the PIN every time you restart the device.
