2nd SIM – Second Phone Number

What is 2nd SIM?

2nd SIM – Second Phone Number is a free Android app that lets you create a virtual phone line without needing an extra SIM card. The app provides a separate number that can send and receive calls and SMS messages over an internet connection, helping you keep personal and professional conversations distinct.

Main features

• Separate number: Choose a new phone number from the list of supported regions and use it alongside your primary mobile line.
• Call and text support: Make voice calls and exchange SMS/MMS messages through the virtual line.
• Wi‑Fi or data operation: The service works over Wi‑Fi, LTE or any mobile data connection, eliminating the need for additional carrier plans.
• International reach: Numbers are available from multiple countries, which can be useful for travelers or people who need a local presence abroad.
• Privacy control: Your real mobile number stays hidden when you use the virtual line for online listings, dating apps, or temporary projects.

How it works

After installing the app, you create an account and select a country and area code for the virtual number you want. The app assigns a number that is linked to your account. All inbound and outbound communication is routed through the app’s servers, using your internet connection. You can answer calls, send replies, and manage messages directly within the app’s interface.

Practical uses

• Business separation: Keep client calls and messages on a dedicated line without mixing them with personal contacts.
• Online marketplaces: Share a disposable number when buying or selling items on classified sites to protect your primary number.
• Travel: Use a local virtual number while abroad to avoid roaming charges and stay reachable to contacts in that region.
• Dating and social apps: Preserve privacy by communicating through a secondary number.

Installation information
