Calling United States
Your first $1 of credit is on us — enough to call United States free for your first minutes. After that it's pay-as-you-go from 0.02 $/min, right from your browser. No app, no SIM, no contract.
Truly-free calling exists, but every option has a catch. Here's the honest picture — and where a few cents a minute beats “free”.
Free — but only if the person in United States has the same app and is online. No use for landlines, businesses, or anyone not on the app.
Reaches any United States number, but international per-minute rates are steep and usually billed by the whole minute.
Cheap headline rates hide connection fees, rounding and balance expiry.
$1 free credit to start, then 0.02 $/min to any United States mobile or landline — from your browser, no app or SIM, no hidden fees.
Enter the country code +1 when dialing United States from abroad.
Add the local phone number (in most countries, drop the leading zero).
Use TwinPhone to connect the call at low per-minute rates.

Honestly, not unlimited-free. App-to-app calls are free only when both people use the same app and are online.

It's the cheapest reliable way to reach United States numbers that aren't on an app.
Your $1 signup credit is roughly 50 minutes to United States at 0.02 $/min. When it runs out you top up only what you need — there's no subscription and nothing expires.
