2nd Line – Second Phone Number

What is 2nd Line?

2nd Line is a free Android app that lets you create an additional phone number on the same device. The extra line works over the internet, so you can send and receive calls and SMS messages without swapping SIM cards.

Main features

• Separate number: Choose a new number for personal or business use while keeping your primary line untouched.
• Call and text over data: Uses Wi‑Fi or mobile data to place calls and send messages.
• Unified inbox: All messages appear in a single interface, making it easy to manage two numbers from one screen.
• Customizable alerts: Set distinct ringtones, vibration patterns, or notification tones for the secondary line.
• Privacy options: Use the extra number for online registrations, marketplace listings, or any situation where you prefer not to share your main contact.

How it works

After installing the app, you create an account and are assigned a virtual number. The app routes calls and texts through a VoIP service, so the communication is delivered over your internet connection. Because the service is independent of your carrier, you can keep the same number even if you change mobile providers.

Practical uses

• Separate work and personal communications on a single phone.
• Provide a dedicated contact number for freelance or small‑business activities.
• Protect your primary number when signing up for online services.
• Maintain a local presence when traveling abroad by selecting a number from another country.

Installation information

Search for "2nd Line - Second Phone Number" in the Google Play Store, tap Install, and follow the on‑screen prompts to set up your account. The app requires an internet connection for activation and ongoing use.

Things to know before installing

• The secondary line relies on data; a stable Wi‑Fi or mobile data connection improves call quality.
• Standard data rates from your carrier may apply when using mobile data.
• Some features, such as call forwarding or voicemail, may depend on the underlying VoIP provider and could be limited in certain regions.

Who may find it useful?
