The Light Phone II supports hotspot tethering, so that you can use the Light Phone II to connect another device like a laptop or tablet to the internet via the Light Phone II.
Hotspot functionality requires an appropriate SIM (ability and data to hotspot).
To create a hotspot for tethering:
Settings > Bluetooth & Wifi > Personal Hotspot > Toggle ON
You have the option to name your network and create a unique password for your personal hotspot network. Once ON, you should be able to see the network on your laptop/tablet and join by entering the designated password.
NOTE: Using the hotspot functionality will drain the battery of the Light Phone II more significantly and if intending to use for extended periods of time, we'd recommend plugging the Light Phone II device into power.
