Magic Jack....LOVE IT!!! Pros: cheap, cheap & cheap. Cons: It works through your computer, so computer has to be on all the time. No limits, no long distance ( you do have to prepay for international calls I think) If your power goes off, you may have to restart...kinda like rebooting your computer. We have an all metal house so cell phone reception is not good in the house most of the time. Magic Jack uses your normal phone hooked up to your computer and saves us having to go outside when our cell receiption is not good. (p.s. you can take it with you when you travel)
