I believe most of the iPhone fans have connected your iPhone/laptop to Wireless@SG before. The troublesome part is that you need to enter your username and password. Also, the tendency of dropping the connection is quite high.
Recently, IDA has released the new Wireless@SGx which allow you to have seamless and secured automatic connection. However, you need to install the Wireless@SG Connect on your iPhone/laptop and configure it. For iPhone, there are three Wireless@SG Connect iPhone applications from the three Wireless@SG operators, namely SingTel, M1 and iCELL. After installing, you need to do a one-time configuration to create a profile with your domain, username and password. Once configured, as long as you are in the vicinity of the Wireless@SGx hotspots, your iPhone will be automatically connected to the network.
Although the data usage price has significantly reduced, it is definitely one way to reduce the data usage.
