RobinPhone

RobinPhone is a web-based calling service that lets you make phone calls to landlines and mobiles in over 175 countries directly from your browser. You buy prepaid credit in amounts of $5, $10, or $25 and pay per minute of talk time, with rates starting at $0.02 per minute.

People use RobinPhone for calls that chat apps cannot make: banks, airlines, hotels, government offices and family members on a landline. It works in Chrome, Edge, Safari and Firefox on desktop or mobile, and you can show your own verified number as caller ID.
