America Unlimited vs magicJack

I bought my first MJ in 2007 and I still use it today though mostly only use it for questionable contacts where I suspect my number will be spammed or added to telemarketing list. I've bought two newer units (MagicJack Plus) over the years and they also work just fine. I used the first magicjack USB dongle with a laptop while driving truck cross country from 2007 to 2012. I used it for all communication with dispatch and to send in my trip and pay information. On occasion I would even send a fax with MJ though I learned I had to turn down the fax speed and only send B&W. I currently use two MagicJack Plus units for my home phone and home business phone lines. A few points I'll make. The older USB style has to be used in a powered USB port while the newer units with a RJ45 jack do not require a PC to use. ALL MagicJack need a high speed internet connection and a very good power source. Once, while messing with the configuration of my router, i did mess up the magicjack and customer service was no help at all in getting it running again, I did work that out on my own. The quality of the Dongle is not the best, but has lasted me since 2007 with repeatedly plugging and unplugging it in the USB port. The AC jack for the MagicJack Plus stopped working after a year though it does work for with a quality replacement I bought. I have the two MagicJack Plus plugged into the same UPS I have the router & modem plugged into which allows me to have phone service during a power loss unless the internet service goes down as well. MagicJack is as easy as getting cheese-wiz out of a can. The only prerequisite is an IQ over 75
