Linked Phone Business Number is a free Android application that lets you create a dedicated business phone line on your existing mobile device. The app provides a second number that works for voice calls and SMS, allowing you to keep personal and professional communications separate.
After installing the app, you select a business number from the available inventory or enter an existing number you already own. The app registers the number with a cloud‑based VoIP service, which routes incoming calls and messages to the app. Outgoing calls are placed through the same service, so the recipient sees the business number as the caller ID.
The app is available for free on the Google Play Store. Simply search for Linked Phone Business Number, tap Install, and follow the on‑screen setup wizard to choose your business number and configure basic preferences.
Entrepreneurs, consultants, real‑estate agents, and any professional who wants a clear separation between personal and work communications will benefit from a dedicated business line without the expense of a second device.
No. The business number operates over the internet, so a single SIM is sufficient.
Yes. If you already own a number, you can register it within the app and continue using it as your business line.
The download and basic usage are free. Additional services such as premium number selection or advanced call routing may involve separate fees, which are presented within the app.
No. The business line maintains its own contact list, keeping personal contacts private.
