WiFi is broadband, but without the wires. With WiFi you can access the mobile internet in more places, whether you're browsing at home, or out and about.
You can use WiFi to access the internet on your phone, tablet or laptop, rather than your 4G or mobile connection.
At home you can use WiFi if you've got a wireless router.
And you can also connect to WiFi 'hotspots' around the country. Hotspots are usually found in public places like cafés, stations and airports, so you can stay online when you're out and about.
How to use WiFi at home
- First, turn on WiFi on your mobile phone, laptop or tablet - go to settings and choose WiFi
- Choose the WiFi network name that matches your home internet connection
- If your home internet connection is protected by a password, you'll have to type that in the first time you want to connect to your WiFi at home
- After that, your mobile phone, laptop or tablet will remember the password and log in automatically.
Using your phone to browse the internet at home on your own WiFi will come out of your monthly home internet allowance.
But using WiFi on the move won't affect your monthly data allowance.
Using WiFi when you are out and about
- First, turn on WiFi in your mobile phone, laptop or tablet's network settings
- You should now see a list of WiFi networks you can connect to
- Some WiFi networks will be free to use and unlocked so you log on to them straight away. But some may be locked, and you might need to pay to use them. You'll also have to get a password to be able to access these
- Hotels, cafés etc will usually provide the password for their WiFi networks if you just ask
- If you need to pay for their WiFi, they'll also give you details of how to do this.
