TwinPhone
TwinPhone is a pay-as-you-go app for cheap international calls and virtual second phone numbers.
Open your browser — or the iPhone app — add credit, and dial any landline or mobile in 145+ countries from $0.02/min.
No SIM, no roaming, no app on the other end: you dial ordinary phone numbers and the person you call answers on their normal phone.
There is no subscription and no contract.
Signing up is free, you pay only for the minutes you use, and the exact rate for the number you dialled is shown before the call connects — no connection fees, no monthly minimum.
You can also rent a virtual second number (US and Canada from $3.19/mo) and take calls and SMS in the browser, keeping your personal number private for marketplaces, sign-ups and verification codes.
Calls are encrypted in transit (TLS + SRTP) and stay stable on hotel or airport Wi-Fi.
Enterprise teams can share one wallet with per-member call logs and CSV export.
