Surfshark – it offers a great server network, impressive speeds, top-notch privacy features, and unlimited simultaneous connections at only around $2 a month (for long-term subscribers). If, however, Surfshark isn't your cup of tea, or you'd be more comfortable with a VPN that's been on the market for longer, consider Private Internet Access and PrivateVPN. Of course, you could find an even cheaper provider for Singapore, but you won't get a nearly as good VPN offer for the money.
