The cheapest ways to call Thailand — compared
Truly-free calling exists, but every option has a catch. Here's the honest picture — and where a few cents a minute beats “free”.
Apps (WhatsApp, Messenger)
Free — but only if the person in Thailand has the same app and is online. No use for landlines, businesses, or anyone not on the app.
Your carrier / roaming
Reaches any Thailand number, but international per-minute rates are steep and usually billed by the whole minute.
Calling cards
Cheap headline rates hide connection fees, rounding and balance expiry.
TwinPhone (browser)
Top up from $1, then 0.17 $/min to any Thailand mobile or landline — from your browser, no app or SIM, no hidden fees.

Frequently asked questions
Everything you need to know about TwinPhone.
Honestly, not unlimited-free. App-to-app calls are free only when both people use the same app and are online. With TwinPhone there's no subscription — top up from $1 (about 5 minutes to Thailand) and calls are 0.17 $/min to any number, with no app or SIM. It's the cheapest reliable way to reach Thailand numbers that aren't on an app.
$1 of credit is roughly 5 minutes to Thailand at 0.17 $/min. You top up only what you need — there's no subscription and nothing expires.
From TwinPhone, just type +66 and the number — we connect it. From a landline, dial your exit code, then +66, then the number (in most countries, without the leading 0).
Calls to Thailand landlines start at just $0.17/min and mobile at $0.17/min. No connection fees, no hidden charges. Billed per minute in 60-second increments (rounded up to the next minute).
No. TwinPhone works directly in your browser — Chrome, Edge, Safari, or Brave. Open the site, add credit, dial +66 and your number, done. No installs, no plugins, no SIM card required.
Yes — we currently rent virtual numbers in the US and Canada, from $1.60/month. Use one as your caller ID so callers see a North American number, or receive incoming calls directly in your browser. Numbers for more countries are on the way.
