20 Best Free Internet Phone Calls Apps

These apps let you make free Wi-Fi calls all around the world

Yes, you really can make free phone calls using the internet. Free internet phone programs let you make free phone calls—sometimes to anyone in the world but other times only to numbers in the US and Canada—using special software.

A free Wi-Fi phone can not be used to make a 911 or similar emergency call. If you need to call 911, use a traditional landline or mobile phone, or a VoIP telephone service that's approved for 911 use.

The free phone call applications listed below are available in four different forms:

  • PC to phone programs are ones that can make a free call from your computer to a real telephone number so you don't even need a telephone yourself.
  • App to phone software are ones that make free internet calls from a mobile device to a real number. These services support making phone calls to any number, even landlines and mobile phones that aren't using the app.
  • PC to PC internet calling is when a computer makes a free phone call to another computer.
  • App to app services run entirely on smartphones or tablets, meaning that phone calls only work if the recipient has the same application installed. This method can not be used to call landlines or other mobile phones that don't have the proper software.

No matter how it works, it's a free call, and these are the best internet phone apps out there.

Most of these apps only work after you download the program to your device. Depending on the app, it will let you make free calls from Android, iOS, Windows, Linux, or macOS.

With Google Voice, you can also get free SMS, make a free conference call, and get free voicemail services.

Free calls you make with Google Voice must be to numbers in the United States or Canada.

Free phone calls with Google Voice are limited to three hours. However, you can continue to make a free call to the same number over and over again.

You just need to confirm your phone number to get started. Once you're using the app, you can start a new conversation to clearly see which of your contacts are also using WhatsApp, after which you can call them for free, no matter where in the world they're located. Group calls can include as many as eight people.

WhatsApp also lets you send videos, photos, your location, and contacts, to other users. End-to-end encryption is supported for all communication within the app.

Because WhatsApp requires the app to make free phone calls, you can not use it to make free calls to phones that don't have the app installed, nor to landlines.

You can use WhatsApp from a computer or mobile device, including Android, iPhone, iPad, Windows, and Mac.
