VoixCall

VoixCall is a browser-based international calling service. Open a tab, dial any landline or mobile number in 160+ countries, and pay only for the minutes you use — rates start at $0.02 per minute, with no app to install, no SIM card, and no subscription. VoixCall exists for the moments traditional apps can't handle: calling a bank, airline, hotel, or government office abroad — real phone numbers that WhatsApp and other app-to-app services cannot reach. It is built for expats calling home, travelers sorting out a blocked card or cancelled flight from another country, NRIs reaching Indian banks from the US, and importers calling suppliers in China without waiting for chat replies. How it works: VoixCall uses WebRTC to connect your browser directly to the regular phone network (PSTN). There is nothing to download or configure — sign up, add credit, and dial. The per-minute rate for every destination is shown before you call, so there are no surprise charges. Credits are pay-as-you-go and do not expire. Key features: - Call landlines and mobiles in 160+ countries from any modern browser (Chrome, Safari, Firefox, Edge) - Transparent per-minute pricing displayed before every call, from $0.02/min - Virtual phone numbers (DIDs) to receive inbound calls, with call forwarding - Caller ID verification, so your calls show your own real number - Call recording (where legally permitted) and call history - Team accounts with shared balance for small sales and support teams calling internationally - iOS app available; Android supported via the browser - Pay by card or UPI (Visa, Mastercard, Razorpay) Compared with legacy options, VoixCall is a practical alternative to Skype (now discontinued) for calling real phone numbers from a computer, and an option for people in countries where Google Voice personal accounts are not available. Compared with carrier international roaming at $2–3 per minute, browser calling typically reduces the cost of a call abroad by over 90%. VoixCall offers a free first call so you can test call quality to your destination before paying anything. New users can sign up and place their first call in under two minutes.
