Suparelay

Suparelay places real phone calls from a browser tab. Type a number, see the price for that exact number, and press call. The phone on the other side rings like any other call, so the person you reach needs no app, no account and no internet.

Calls reach landlines and mobiles in 200+ countries, from about 2 cents a minute. Prepaid credit from $5, charged per started minute, and an unanswered call costs nothing. No subscription, and credit never expires. US toll-free numbers connect from abroad, and a keypad works during the call for automated phone menus.
