When it comes to ATMs, you can find them at all malls and draw funds from foreign debit cards through them. You can also find money-changers in most shopping centers as well as throughout the whole country. You’d be surprised how many are open for 24 hours and offer competitive rates for your Exchange. Little India, in particular, is a good place for changing your money when needed.

You can also purchase SIM cards in Singapore from post offices, telecom shops, and 7-Eleven convenience stores, but be sure to take your passport with you, as you will be required to show it to purchase.

As far as Wi-fi networking goes, most hotels and hostels offer internet, in many cases for free. The island has an extensive broadband network with tons of hotspots throughout the country.
