Boss Revolution is a popular pay-as-you-go calling app, but it is designed around the US market and lives inside a mobile app bundled with money transfer and mobile top-up. If you are not in the US, or you simply want to call from a laptop without extra products, it is more than you need. Hyallo focuses on one thing - cheap calls to phones - and runs in any browser, anywhere.
Boss Revolution is a service from IDT, widely used in the US, that bundles international calling with mobile top-up and money transfer. Its calling product offers pay-as-you-go rates to many countries, delivered through a mobile app and aimed primarily at immigrant communities in the United States.
Common reasons: you are outside the US, you want to call from a computer, or you would rather not install an app stuffed with extra products. Hyallo is a focused, browser-first option that does exactly one job well - calling phones cheaply, from anywhere.
Hyallo works from any country in your browser and can call 180+ destinations. It is not tied to the US market the way Boss Revolution is.
No. Hyallo is browser-based - there is no app to download and no extra products bundled in.
Yes - your first call is free, with no credit card required to start.
