The magicJack phone serves as a device that plugs into a computer's USB port and enables the user to make calls through the computer's Internet Protocol Address. The device allows users to make unlimited phone calls to the United States and Canada, even if they are in a foreign country.
The magicJack company has a couple different products, including the standard magicJack and the magicJack plus. The magicJack plus does not require the use of a computer, but still needs a wireless or wired Internet network. The devices allows users to make calls without having a phone plan, because the calls go through the Internet to landlines based at the company's headquarters in the United States. This makes it possible for overseas individuals to call the United States or Canada without paying for an international calling plan.
The magicJack devices use a system called Voice Over Internet Protocol, which allows users to both receive incoming calls and make outgoing calls through an existing Internet connection. Calls can be made through the computer or through a phone that is linked with the device. Certain types of calls made from the magicJack device, such as calls to conference lines, through calling cards and to some areas in northern Canada and Alaska, require special pre-paid minute subscriptions.
