Calloza

Calloza lets users place international phone calls directly from a web browser without installing any software or maintaining a subscription. After adding credits, callers can dial any of the supported 150 + destinations, with rates displayed per minute for each country and transparent pricing that shows the cost before the call is placed. The service provides HD voice quality that adapts to connection speed and uses end‑to‑end encryption to keep conversations private.

The platform is intended for individuals who need occasional or regular overseas communication, such as expatriates, travelers, and families staying in touch across borders. Because it works on any device with a browser—including iOS and Android phones—users can keep a single account and call from wherever they have internet access. Support is available around the clock, and the service claims to serve millions of customers worldwide.
