### [Fonable](https://www.g2.com/products/fonable/reviews)

Fonable is a browser-based international calling service that helps users call real landline and mobile phone numbers abroad without a SIM card, native app, or monthly phone-system subscription. Fonable is designed for individuals, professionals, and small teams that need outbound international calling from a web browser. Users sign in, add pay-as-you-go credits, enter an international number, and place calls over their internet connection. The product focuses on calling real phone numbers rather than app-to-app voice or video calls. Fonable is used by travelers, expats, immigration professionals, recruiters, consultants, real estate agents, travel agents, agencies, and globally active small businesses. Common use cases include calling airlines, banks, embassies, government offices, hotels, customer support lines, international clients, overseas candidates, and service providers that require a phone call. Main features include: - Browser-based calling: users can place calls from a supported web browser without installing a desktop or mobile calling app. - International outbound calls: Fonable supports calls to landlines and mobile numbers in 180+ countries. - Pay-as-you-go pricing: users add credits and pay by the minute instead of buying a monthly calling plan. - No SIM requirement: calls are placed through the browser session and internet connection, not a mobile carrier SIM. - Simple account setup: users sign in, add credits, and dial supported international numbers from the web dialer. Fonable is not a full contact center or enterprise PBX. It is better suited for users who mainly need straightforward outbound international calling without extensions, desk phones, long-term contracts, or complex phone-system setup. For occasional international calls, customer-service calls, and cross-border professional communication, Fonable provides a focused web softphone for calling real phone numbers from the browser.
