What is Callzo?

Callzo is a browser-based international calling platform designed for freelancers, agencies, remote teams, recruiters, and businesses communicating with clients in the US and Canada.

Users can get dedicated US or Canada virtual numbers and make or receive calls directly from their browser without needing a SIM card, roaming plan, or hardware setup.

The platform focuses on simple setup, transparent pricing, and lightweight business communication workflows. Features include browser calling, incoming and outgoing calls, call history, usage tracking, team management, and flexible top-up plans.

Callzo is built for users who need a reliable and straightforward way to handle international communication without the complexity of traditional enterprise telephony systems.
