Internet in Singapore is free, but….you need to register before you can use Wireless@SG. Of course you’ll find more free wireless networks in Singapore, but Wireless@SG is covering most of the city. Problem is that you can’t do it in Singapore online if you don’t have working mobile phone with local number.  So before you will head to Singapore, check Wireless@SG registration information, as most likely you will need to register in person on arrival.
