TwinPhone is a browser-based calling and virtual phone number service for people who need to reach real mobile and landline numbers from abroad.

It is built for travelers, expats, remote workers, founders, support teams, and international users who need a simple way to call without changing a SIM card, relying on roaming, or setting up complex VoIP software.

Unlike app-to-app messengers, TwinPhone connects to ordinary phone networks. The person receiving the call does not need TwinPhone, an internet connection, or a special app. They simply answer on their regular phone.

TwinPhone works directly in the browser. Users can open the website, enter a phone number, review call details before dialing, and place a call over the internet. An iOS app is also available for users who prefer calling from an iPhone.

The service is designed for real travel and remote-work conditions. Adaptive WebRTC audio helps maintain call stability on slow or unreliable Wi-Fi, while TLS and SRTP encrypt call signaling and audio in transit.

TwinPhone also offers optional US and Canadian virtual phone numbers. These numbers can receive incoming calls and inbound SMS, making them useful for account access, customer communication, travel logistics, privacy, and keeping a stable contact number while abroad.

Outbound calls are pay-as-you-go, with the exact rate shown before each call. Calls to the US and Canada start from $0.02 per minute. Optional US and Canadian virtual numbers start from $3.19.

Common use cases include calling banks, airlines, hotels, clinics, government offices, delivery services, customer support lines, family members, customers, and business contacts.

TwinPhone is also a practical Skype alternative for people who need to call real phone numbers internationally from a browser.
