MagicJack is a USB device that connects to a wireless router or computer to provide a Voice over Internet Protocol telephone service. The price of the device includes one year of service.
Users can connect the magicJack to a wireless router by using an USB adapter that also has a jack for a phone line. This allows phone calls over an existing Internet connection.
Alternatively if there is no wireless adapter available the USB adapter can connect directly to a PC or laptop to provide a phone line. With this option the phone service operates only when the PC or laptop power is on.
