Weve had magicjack for also about 6 mo's.
In fact at first we thought it was great so we bought 2! The reality is, the technology is severely lacking. If you run into a glitch they will only have a chat line to help you. I have personally spent 16 total hours on chat trying to reset the mj# that suddenly quit working. Unly because I was in Europe and they disconnected me from my family.
Then I had another magicjack sent to me and suprise suprise, the same thing happened mysteriously quit working!
Another 2 full days on chat, for the same reason to no avail!
Save yourselves countless hours online trying to repair a product that they will not repair no matter how hard you devote yoursellf to it.
Nice idea, but just save yourself the grief and the money, do yourself a favor, there are far more reliable means of comunication, and far less frustrating, trust us on this.
