Windows Phone’s Wi-Fi Sense allows users to share a Wi-Fi with friends.
- Navigate to settings.
- Tap on Wi-Fi.
- Tap on the network you have connected.
- Check “Share network with my contacts”.
This will share the network with your contacts. Remember that Wi-Fi Sense never shares the password with your contacts. It always masks the password to any user to connects via Wi-Fi sense.
Keep in mind that if you are sharing the Wi-Fi network of your home, then your contacts near by your home will be able to use your Wi-Fi free of cost. Read this how to explaining on setting up hotspot sharing.
Your friend will be able to use your shared network only if he / she has enabled Wi-Fi Sense.
