100% Free Global Calling

With Duo Call, you can make free international phone calls without contracts or hidden charges. It's simple: install the app, earn or buy credits, and start calling any mobile or landline number—even if the other person isn’t using Duo Call or doesn’t have an internet connection.

Free Credits, No Cost to Start

Every new user receives bonus credits upon signing up. After that, you can earn more credits in fun and easy ways:

· Spin the daily lucky wheel

High-Quality International Calls

Call Recording for Privacy & Convenience

With built-in call recording, you can capture important conversations or save special moments. All recordings are stored locally on your device—never uploaded to the cloud—giving you full control and privacy.
