Connecting to the internet.

There are two ways for you to connect to the internet on your phone. You can connect by using our 3G network or by using Wi-Fi.

If your phone came directly from Three, you shouldn't need to do anything to use our 3G network to connect to the internet. All our phones come with the internet already installed and ready to use. If you're having trouble, you'll need to make sure that our network is enabled and the internet settings are correct. Also, if you're not using Wi-Fi you should switch it off to avoid any connection issues and save your battery.

If you're using a non-Three phone, you'll need to update your internet settings.
