I bought a Magic Jack a couple of weeks ago. It's certainly got the right name--it works just like magic!! The device was $19.99 and $20.00 for a year's prepaid service and I brought it home and followed the instructions to set it up and started using it.
WOW!!! All I can say is WOW!! It works perfectly and gives me crystal clear phone calls all over the USA with no extra fee except for $20 a YEAR for unlimited local and long distance calls without burning up my cell minutes. It's great for the campaign because I can call everywhere and for the paltry sum of $1.66 a month it's a LOT cheaper than Skype or any of the other VOIP services and it works incredibly well. I am totally impressed by it, I was able to choose any area code I wanted and I could have chosen my own number for a nominal extra fee if I had wanted a special set of digits. It travels and I can make phone calls from my computer at any place that has a wireless internet hookup. I highly recommend it for travelers--and because I just plug the phone into the jack, it's comfortable to use although taking a phone with you could take up some space although you could just pull the hotel phone out of it's wall jack and plug it into your Magic Jack and use it. I give it my highest recommendation and would buy it again--and it's a bargain at twice the price!!
