Suparelay is a browser-based phone calling service for making domestic and international calls to landlines and mobile phones from a computer, tablet, or phone. Enter a number, check the rate before dialing, and place the call over the internet using your browser’s microphone. Neither you nor the person you call needs to install an app or use a SIM card for the call to connect to an ordinary phone. Suparelay provides pay-as-you-go calling with prepaid credit, call history, and a record of each call’s cost. Unanswered calls are not charged, and unused credit does not expire. During a call, use the keypad for automated phone menus or mute the microphone as needed. Suparelay can be used for international calls to family, banks, businesses, airlines, hotels, and other landline or mobile numbers.
