How to Call Vietnam from the U.S.

Calling Vietnam from the U.S. is affordable and easy.

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

  • First, dial 011 to exit the U.S. telephone system.
  • Next, dial 84, which is the country code for Vietnam.
  • Now dial the local phone number, which is either 9 or 10 digits.

Calls made through the Ooma Mobile app do not 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.

If you encounter any issues or have any further questions, feel free to contact Customer Support at https://support.ooma.com/.

Whether it’s Ho Chi Minh City or Hanoi, Ooma’s international calling plans are a great way to save money calling Vietnam.

The Ooma World Plus Plan offers unlimited calling to Vietnamese landlines and mobile phones for just $25.99 per month. It also provides unlimited calling to landlines in 70 countries and mobile phones in 40 countries.

Call Vietnam for Free

Ooma’s World Plans include unlimited calling to landlines and mobile phones around the world, but you can also use Ooma Telo to make free calls. That’s because all Ooma-to-Ooma calls are 100% free regardless of how long you talk. So you can chat with your grandparents in Vietnam as long as you want and it won’t cost a penny.

Better than Calling Cards

Using an international calling card for Vietnam can be affordable, but they can be a headache since you need to recharge them. Standard rates, on the other hand, can be expensive.

Ooma’s international options are not only more affordable, but less of a hassle. You’ll also be able to speak to multiple countries, so you can keep up with your old work buddies in China and family in Vietnam without worrying about racking up a high phone bill.

Use Ooma to call Vietnam

Ooma’s affordable calling options make it a popular choice to call Vietnam. It all starts with Basic Service and Premier Service’s affordable rates.

With both Basic and Premier Service, calls to Vietnamese landlines and mobile phones are charged at $0.092 per minute. International calls with Basic Service are prepaid, and deducted from your balance.

Premier Service may have the same rates as Basic Service, but it comes with a number of added perks. Users get powerful call-blocking tools to battle robocalls, the Ooma Mobile app for on-the-go calling, voicemail access through email, unlimited calls to Canada and Mexico plus more for just $9.99 per month. You pay applicable monthly taxes and fees.
