Technology has made it easier and more convenient for people to communicate. Now there are several ways of communicating for free. Earlier, you could only make free PC-to-PC calls but now, thanks to the Internet-enabled cell phones, you can make free PC-to-mobile and mobile-to-mobile calls as well. Use any VoIP service on your computer or phone and stay in touch with family and friends without paying anything at all.
Sign up for a VoIP client, such as Barablu, Fring, or Nimbuzz. By downloading and installing any of these software applications, you can register and make free calls to friends on their cell phones. Your friends must have a VoIP client installed (such as Barablu, Skype, Google Talk, Yahoo Messenger etc). VoIP software lets you make free calls to your friends, regardless of which VoIP client they use.
Type in your friend’s VoIP number or ID into the VoIP client that you are using.
Click on the “Dial”/“Call” button for connecting the call. Your friend on the other end will hear a ringtone on his phone. Once he answers the call, you will be able to talk for as long as you want.
