As well as being a hot-shot cameraphone, the Sony Ericsson C905a is also well equipped for online connectivity. Not only does it support HSDPA high-speed 3G mobile data, it can also connect to the internet wirelessly using a Wi-Fi connection.

You can use Wi-Fi to get a high-speed wireless connection to the internet on your home Wi-Fi network, at work, or via public access Wi-Fi hotspots. It's simple to use. First, you need to switch on the phone's Wi-Fi function. You can then connect to nearby networks to which you have access, and connect to the internet using the phone's browser.

For accessing protected Wi-Fi networks you will need a passphrase or key from the Wi-Fi network owner. For public hotspots you may not need a passphrase or key, but may have first have to log on to the operator's service to get internet access.

Within the C905a's Wi-Fi menus, you can also select your most used  networks to connect automatically when the phone 's Wi-Fi is switched on within range.
