How to Call Thailand from the U.S.

Making an international call is easy.

To call Thailand, 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 66, which is the country code for Thailand.
  • Next, dial the local number, which is either 8 or 9 digits.

Keep the following considerations in mind when calling Thailand. You may encounter listed numbers beginning with a “0.” That 0 is a “trunk code” and is part of Thailand’s national dialing format (just like how we in the U.S. sometimes use “1” when dialing a long distance number). Dial only the numbers after the 0 to ensure the call goes through properly.

Mobile numbers in the country begin with either an 8 or a 9. Unlike in other countries, Ooma does not charge a different rate for mobile numbers in Thailand, so this will not result in a difference in per-minute charges if you are not an Ooma World or World Plus subscriber.

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. If possible, connect to a Wi-Fi hotspot to place calls in order to minimize data usage.

Calling another Ooma customer, regardless of which country they’re in, is free of charge for as long as you want to talk. If you encounter any issues or have any further questions, feel free to get in contact with us via our Customer Support website at

With both the Ooma World Plan and Ooma World Plus Plan, all calls to Thailand, regardless of whether it’s a landline or mobile phone, are unlimited. In order to decide which plan is best for you, it’s helpful to review both international plans and see which other countries are included.

In total, the Ooma World Plan gives you unlimited calling to landline numbers in 60 countries and mobile numbers in 10 countries for $17.99 per month. The Ooma World Plus Plan adds an additional 10 countries for landlines (70 in all) and 30 more countries for mobile numbers (40 in all) for $25.99 per month.

Call Thailand with Ooma

It can often be expensive and difficult to call Southeast Asia, but with Ooma Telo, it’s affordable and easy.

Using Ooma’s Basic Service or Premier Service, calls to both landline and mobile numbers are billed at the same $0.073-per-minute rate, meaning a 10-minute phone call costs $0.73. Basic Service is prepaid, so charges are deducted from your prepaid balance, while with Premier Service, the per-minute charges are added to your bill in addition to the $9.99 monthly fee.

While Basic Service has no monthly fee for crystal-clear nationwide calling, Premier Service offers a whole host of additional features for a low monthly charge. For example, Premier Service customers get powerful call-blocking tools to protect them against telemarketers and robocalls, as well as an Instant Second LineTM for making and receiving calls when your primary line is in use, the Ooma Mobile app for making calls from your mobile phone anywhere you are, voicemail access through email and text notifications, free unlimited calling to Canada and Mexico, plus many others that Basic Service doesn’t provide.

Ooma’s rates are much more reasonable than traditional long distance providers. MCI’s Global Connection long distance plan not only costs you $4.00 per month to get its best rates but an additional $0.25 per minute to make the call itself, which means the actual per-minute rate is much higher.

Ooma-to-Ooma calls are 100% free regardless of the amount of time you talk, so if your contact in Thailand is also an Ooma customer, you can talk as long as you want and it won’t cost a penny. You’ll also have calls in crystal-clear HD voice, which is much better quality than standard telephone lines can provide. You pay applicable monthly taxes and fees.
