The MagicJack does not work as advertised. I have had the device for several weeks and spent numerous hours on the chat line (no direct phone assistance) to resolve the problem. The connection is interrupted every 3 minutes with a pause to the service. The interruption is about 2 seconds long and disrupts the conversation. If quality service is important to you do not purchase this device.
If you want a cheap communication tool and you do not care about the quality, this device is for you.
