Acquiring a free online phone enables you to make free international calls without the hassle of going through the ordinary telephone system and, naturally, without the expense. With the rapid advancement of internet technology, making free international calls is now easy with a free online phone.

The simplest free online phone is a computer with an internet connection. Many services have been available for years that enable international voice communications between one computer and another. Skype, Yahoo Voice and Windows Live Messenger are among the more well-known services that offer computer-to-computer international communications.

Skype is the service that made free international communications a reality for most people all over the world. It is an application software, downloadable for free, that enables one person to talk to another person via their respective computers. As long as the communication is via computers, the Skype service is free. However, if the communication is from a computer to a landline or mobile, Skype charges a fee.

Some of the other free online phone services with which to make free international calls are Tuitalk, EvaPhone, Freebuzzer, iCall and Google Voice. Each of these services has its own advantages, limitations and restrictions.

Tuitalk lets you make free phone calls to around 40 countries. You need to download their free software before you can make use of the service. The phone calls have a time limit, but with most countries you can make free phone calls for 6 minutes. There is also a limit to the number of free calls you can make in one day.

Evaphone is another free online phone service that can be used to make calls from your computer to almost any phone in the world. However, Evaphone has extremely short time limits per phone call, from 10 seconds to 1 minute, making it practical for only short, urgent messages. You can also make only 2 free calls a day.

A third free online phone service is Freebuzzer. You can make free international calls to any country in the world, but the call must last not longer than 2 minutes. There is also a limit of 3 free phone calls a day.

If you are calling a number in the USA or Canada, iCall is a free online phone service you can use. Free phone calls are disconnected after 5 minutes. However, nothing can prevent you from dialing the number again as often as you want. ICall does not allow free phone calls from outside the USA or Canada.

Another free online service to numbers in the USA and Canada, Google Voice allows you to make phone calls up to 3 hours. Web apps are available for any browser, and for mobile browsers including Android, Blackberry and iPhone sets.
