It’s possible through certain second phone number apps like Google Voice.

It’s worth noting that the cheapest phone service may not always be the best option, as they may not have the specific features you’re looking for.

What is a second phone number app?

A second phone number app is a software application that, once installed on a mobile device, allows the user to have a separate, fully functional phone number alongside their primary number. It operates on the same device without the need for additional SIM cards or hardware. This is made possible through Voice over Internet Protocol (VoIP) technology, which allows for the transmission of voice communications and multimedia content via the Internet.

These apps offer a level of versatility and privacy that can be valuable in various scenarios, including personal use, business communications, or situations where a temporary number is needed. For instance, you might use a second number for online selling to keep your primary number private, or a business may use it to separate personal and professional communications.

The features available vary by app, but common functionalities include:

  • Call Forwarding: This feature allows incoming calls to the second number to be forwarded to your primary number or another designated number. This can be particularly useful for businesses with multiple team members handling customer inquiries.
  • Custom Voicemail Greetings: Some apps allow users to set a different voicemail greeting for the second number. This can be beneficial for providing a more professional image or delivering specific information to callers.
  • Text Messaging: Many second phone number apps support text messaging, allowing users to send and receive texts using the second number.
  • Call Blocking: This feature enables users to block specific numbers or unidentified callers from reaching the second line.
  • Contact Management: Some apps offer enhanced contact management features, allowing users to maintain separate contact lists for their primary and secondary numbers.
