The Hilton has fairly slow internet service in its Executive Lounge tucked away in the corner. Not that great. Let them know that many of their competitors have high speed internet, for instance, the Conrad. I find the hotel ok otherwise and well located, but everyone's different.
One provider to hotels in SIN is
www.net2room.com. Their site lists the facilities for which they are providers. There are a couple of internet cafes within a few minutes walk of the Hilton.
The Conrad also has Wi-Fi, for a fee, in some of its public spaces, which I have no trouble connecting to using a Cisco card.
In addition, SIN has at least one Wi-Fi provider for public spaces,
www.bluengine.com. Their site discusses hotspots.
AT&T Global has two local v.90 access numbers, 68251800 and 68251888 .
