What is Bluetooth® wireless technology?
Bluetooth Wireless Technology is a short-range communications technology using encryption for high security data/voice transmission. ^ BACK TO TOP 2. Is it safe to use Bluetooth devices? I have heard they can allow unauthorised connections. For Bluetooth security reasons, once you have set up your Bluetooth devices we recommend turning OFF the visibility option in the Bluetooth Menu of your phone so that other Bluetooth users cannot see your phone. This only applies to a few (mainly older) Bluetooth enabled phones as most new phones have better security.
