Call Any Phone From Your Computer

Suparelay is a browser-based phone service for calling landlines and mobile numbers worldwide. Open a tab, enter a number, and the call rings on an ordinary phone—no installation required on either end. Rates start at $0.03–$0.04 per minute depending on destination, with pricing shown before dialing. Calls that don't connect cost nothing. The interface displays call history, remaining balance, and per-call costs in one place, with features like keypad access for phone menus and mute control. Built to simplify international calling by buying minutes directly from networks rather than through resellers.
