How do free business VoIP plans work?

When a VoIP phone system is free, this generally means that a company will provide you with free service and a single free phone number.

Free business VoIP plans are typically created for startups and small businesses. If you own a mid to large sized business or have multiple departments within your business, you may want to consider paid business VoIP systems as they are better equipped to manage large call centers and customer support departments.

Pros and Cons:


  • Free service and phone number.
  • Free VoIP plans are ideal for startups and micro businesses.


  • Minutes and messages are limited.
  • Not suited for mid to large sized businesses.
  • Only provides one phone line.
  • Unable to contact emergency numbers.

Should you use a free VoIP service?

Before you choose a VoIP service provider, consider the pros and cons of a free business VoIP plan and research the VoIP features you'll need to operate efficiently, then compare your findings with your business' VoIP system requirements.
