To make cheap international phone calls via the Internet, you can utilize one among the many Internet-based VoIP services out there.
All of these VOIP calling services allow you to place a phone call via one or more of your preferred communication devices:
- Computer: Instant messaging tools enhanced with VoIP capabilities like Skype, Yahoo! Messenger, Live Messenger and others, allow you to make cheap international phone calls among other users (e.g. Skype users can call other Skype users for free), but also let you call landline or mobile phones for very low rates.
- Mobile phone: Recent mobile phones and smartphones that support fast networking technologies like 3G or HSDPA can seamlessly make international calls. You only need to download and install the mobile application of your preferred service to get started.
- VoiP-enabled telephone: Several manufacturers produce telephones or external phone adapters that support the VoIP protocol. You can call the world for free just like you would make any other standard domestic call. The only difference is that your phone must be connected to the Internet either via Wi-Fi or via a standard Ethernet cable.
Once restrained only to computer-computer communications, the VoIP protocol has come of age during recent years and now allows you to get in touch with other people also from your landline phone, your Internet-connected mobile and any other device that are able to connect to the web at much lower rates than with traditional telephones.
Let's see an example of how you can save money to make an international phone call using Skype, one of the services that has greatly fostered the adoption of VoIP technology all over the world.
- The first step is to register online with Skype and to buy some pre-paid phone credit. You can do this by using your credit card or an online payment service like PayPal.
- With that phone credit you can now dial, directly from your computer, any telephone number, landline or mobile out there on the planet while paying much lower rates than those charged by your traditional telecom provider.
What many people do not know yet, is that services like Skype, can be accessed not only from desktop PC or laptop but also from mobile phones that are Internet-enabled, as well as from traditional telephones when matched to one of these low-cost international calling services.
In essence, you can make cheap international phone calls by using any of the services reviewed in this guide, some of which allow you to call (and some even to receive) from your computer, while others allow you to make phone calls directly from your mobile phone or traditional landline.
To make it easier for you to evaluate the best service to call the world for free, in this guide you will find a comprehensive mindmap, a comparative table and a set of mini-reviews to help you make the right choice.
Here the criteria I have used for my comparison:
- Receive phone calls, not just make phone calls.
- Send / receive SMS text messages
- Voicemail service
- Availability of a mobile phone version
- Operating system supported
Here's a roundup of the best tools to call the world for free available out there.
N.B.: The present list of tools is updated on an ongoing basis. You may want to bookmark this page (simply hit CTRL+D on your Windows keyboard or CMD+D on your Mac keyboard), as I am always adding more services.
As a side note, I would always recommend to use a headset if you want superior phone call quality. In fact, even a headset is not compulsory, having an external mic and headphones can greatly help in reducing echo and ambient noise.
