Suparelay

Suparelay makes international phone calls from a browser tab, for work and personal calls to numbers that cannot answer an internet calling app: clients, suppliers, banks, airlines, embassies and offices abroad. Type the number, see the price for that exact number, press call, and an ordinary landline or mobile rings. The person you call needs no app, no account and no internet. Calls reach 200+ countries and territories from about 2 cents a minute. Prepaid credit from $5, charged per started minute, and nothing if they do not answer. No subscription, and the credit never expires. A keypad works during the call for automated phone menus, and call history shows the date, duration and charge of each call.
