How to Get 3G Data Free on My Cellphone Wi

1. Access the Wi-Fi configuration settings on your cellphone. The specific way of performing this step depends on the make and model of the phone. For example, for an iPhone 4, press the 'Home' button and slide your finger across the screen to unlock it. Tap 'Settings,' then 'Wi-Fi.' The phone will display a list of wireless networks in range.
2. Find a free network you want to join. The network's operator typically publicizes the name of the network so that potential users know which network to join.
3. Direct your phone to join the free Wi-Fi network. For example, for an iPhone 4, tap on the list entry for the network you wish to join. If the network happens to be protected, the iPhone will prompt you for a password or passphrase (also obtainable from the network operator.) Type the password or passphrase, then tap 'Connect.' Wait until the iPhone joins the free Wi-Fi network.
