Is your phone bill starting to add up? Want unlimited calling but don't want to pay a hefty price to get it? Well, you're in luck because there's a way for you to get unlimited U.S. calling for less than $10 with VoIP.

What Is VoIP?

VoIP, which stands for Voice over Internet Protocol, is the method of sending voice communications (phone calls) through the Internet rather than traditional phone lines. With VoIP you can continue to use your same phone with your current phone number, and VoIP's call clarity and quality are identical, if not better, to your traditional phone service.  Since the calls are routed through the Internet, VoIP services are cheaper and include a lot more features — such as caller ID, voicemail and other VoIP-specific features — for free.

Our Top Picks for VoIP Phone Service

Unlike traditional phone services, the prices for VoIP services are very upfront and add up to less than $10 per month. We've reviewed the leading VoIP services to see which services are the best. Below are our top choices for unlimited calling under $10 per month.

It should be noted that VoIP customers are required to pay additional taxes and fees for services such as Enhanced 9-1-1, which registers your phone number to your home address so emergency services can locate you in the event that you dial 9-1-1. These taxes and fees are not costly at all and usually add up to less than $3 per month.

Is VoIP difficult to set up?

VoIP is as easy to set up as your traditional phone. When you sign up for a VoIP service, the service will send you an analog adapter that converts your voice and allows it to travel through your Internet router and be received on the other end of the call.unlimited calling

To set up VoIP, simply connect your touch-tone phone to the adapter and then connect the adapter to your Internet router. The image on the right displays the standard VoIP adapter that's provided by the VoIP service.

Since the adapter only takes up one Ethernet port, you'll still be able to use the other ports on your router for anything you wish. It's important to note, contrary to what some think, you do not need to have your computer on in order for your VoIP service to work. You simply need to have some sort of high-speed Internet and connect the adapter to the Internet router and touch-tone phone.
