Second Phone Number is a free Android app that lets you create and use a virtual phone line on your device. The app provides an eSIM‑based number that works alongside your regular mobile number, enabling you to send and receive calls, SMS and chat messages without needing an extra SIM card.
After installing the app, you create a virtual profile by selecting a country code and confirming the number through a short verification step. Once the number is active, the app routes incoming calls and messages through the eSIM service, displaying them inside the app’s interface. Outgoing calls and texts are sent using the virtual number, so the recipient sees the secondary line instead of your primary mobile number.
The app is available for free on the Google Play Store. Search for "Second Phone Number" by Municorn, tap Install, and grant the permissions required for call and messaging functions. No additional hardware or physical SIM is needed.
Freelancers, small‑business owners, frequent online sellers, travelers, and anyone who wants to keep their personal phone number private can benefit from a secondary virtual line.

Yes. During setup you can select from the list of supported country codes.
The core functionality—creating a virtual number and basic calling/texting—is provided at no cost. Some premium services or international calling rates may incur charges.
