How to Call Singapore from the U.S.

Making an international call to Singapore is easy.

You can use either your Ooma Telo-connected home phone or the Ooma Mobile app to call Singapore.

  • First, dial 011 to exit the U.S. telephone system.
  • Next, dial 65, the country code for Singapore.
  • Now dial the 8-digit local phone number, which is 8 digits.

Calls made through the Ooma Mobile app don’t use any minutes or incur international charges on your wireless bill. These calls are instead routed over your data connection and could count against your data allotment if you’re not on an unlimited plan with your carrier. To minimize data usage, connect to a Wi-Fi hotspot.
