Call Southeast Asia from the USA in Your Browser

In short

You can call Southeast Asia from the USA straight from your browser with StartACall, no app download, no SIM card, and no phone number needed to dial out. Reach the Philippines, Vietnam, Thailand, Indonesia, Malaysia, Singapore, and more on a pay as you go, per minute basis with end to end encryption. Just open Chrome, Safari, Edge, or Firefox and dial.

How to call Southeast Asia from the US

Open StartACall in any modern browser on your laptop or phone, enter the full international number, and connect. For Southeast Asian destinations you dial the country code first: the Philippines is 63, Vietnam is 84, Thailand is 66, Indonesia is 62, Malaysia is 60, and Singapore is 65. Drop the leading 0 of the local number after the country code.

Outbound calls require no phone number of your own and no contract. You pay per minute as you go, so a quick check in with family in Manila or a supplier call to Ho Chi Minh City costs only the minutes you actually use.

Why use a browser instead of an app

There is nothing to install and no SIM card to swap, which matters when you are calling across a 12 to 15 hour time difference and just want to dial fast. It runs on Chrome, Safari, Edge, and Firefox on Windows, Mac, Android, and iPhone, so the same account works from your office desktop and your phone.

Every call is end to end encrypted, which keeps both personal and business conversations private. That makes it a solid fit for remote teams coordinating with offices in Singapore or Kuala Lumpur, freelancers working with clients in Bangkok, and anyone keeping in touch with relatives across the region.

Receiving calls back from Southeast Asia

If you also want people in Southeast Asia to call you, add a US or Canada digital number to your account for roughly $2.14 to $5 per month. Contacts then reach you on a normal number while you answer in the browser, no second device required.

Frequently asked questions

Outbound calls are pay as you go and billed per minute, so you only pay for the time you spend on the call. There is no monthly fee and no contract for dialing out.

What country codes do I use for Southeast Asia?+

Dial the country code before the local number: Philippines 63, Vietnam 84, Thailand 66, Indonesia 62, Malaysia 60, and Singapore 65. Remember to remove the leading 0 from the local number after the code.
