If you want a way to call friends and family across the globe on the cheap, MagicJack can be a good investment, says the website ConsumerReports.org. You can use MagicJack on Wi-Fi-enabled computers that are connected to broadband Internet.
MagicJack is a USB device for your computer that effectively turns your machine into a phone that can call numbers all over the world via the Internet. This may be accomplished by using your computer with a headset and the MagicJack device, or using your computer and a traditional telephone handset connected to the MagicJack device. MagicJack charges a yearly subscription fee that provides free calling in a variety of countries. For countries not covered by the base subscription fee, MagicJack offers discounted per-minute calling rates.
MagicJack may be used with a computer that has a Wi-Fi connection. The Wi-Fi network must be linked to a broadband Internet connection such as DSL or cable. Once a computer is connected to the Internet, the MagicJack software interface appears and a user may dial the number of his choice. This phone number may be a landline telephone, a cellphone or even another MagicJack device, since MagicJacks come with a unique phone number.
MagicJack will not work with dial-up and satellite Internet connections. The company's website also states that Internet connections must have a minimum upload speed of 128 kilobytes a second.
Users of the MagicJack should keep in mind that the device is totally dependent on the integrity of your Internet connection. If the connection hiccups or cuts out entirely during a call, the call will end and you will have to redial.
