GPRS on laptop throughout Singapore at 20 dollars per month
M1 offers this subscription which wife enjoyed it very much. A GPRS modem let you access internet literally anywhere in Singapore. Configure-less and light, HuaWei Vodafone is a delightful addon to any mobile PC. Now I can blog (not work) in MRT from Raffles Place to Woodlands. Truly mobile.
Update:Paddy says, For S$20 it is really worth for checking emails and some light surfing of the net with considerable okay speed.
Wireless@SG simply cannot make it even through it is free. Logging in is already an uphill task.
