How to Call South Korea from the U.S.

Making an international call to South Korea is easy.

To call South Korea, you can use either your Ooma Telo-connected home phone or the Ooma Mobile app.

  • First, dial 011 to exit the U.S. telephone system.
  • Now dial South Korea’s country code, which is 82.
  • Finally, dial the local number, which can be 6 to 12 digits.

Landline numbers in Seoul are 8 digits, while landline numbers in the rest of South Korea are 9 digits. Mobile numbers range from 6 to 12 digits and all begin with 1.

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

Free Calls

Ooma’s World Plans give you unlimited international calls to South Korea, but if your contact in Seoul is also an Ooma user you won’t need the plan to make free calls. That’s because all Ooma-to-Ooma calls are 100% free regardless of how long you talk. You’ll also make calls in crystal-clear HD, which provides much better audio quality than standard telephone lines.

Better than Calling Cards

International calling cards are an affordable way to call South Korea from the United States, but they’re not the most convenient. You have to make sure they’re all charged up before using them.

Ooma’s international plans are not only more affordable than traditional phone plans, they’re more convenient than calling cards.So you can spend hours on the phone with grandparents in South Korea and friends in Indonesia without racking up a high phone bill.
