It depends on which version of the device you have. If you have the regular Magic Jack, then yes, you must keep your computer on to use it. If you are expecting a call, it cannot be off. If you have the Magic Jack Plus, then you only need to leave your router on, since it can plug into a network socket rather than just a USB port.
Absolutely, I do everyday!
It has a chip inside that receives same signal as a phone line. Just plug it into the wall or you can use the computer to plug it in to.
