As with all technology, it keeps advancing, and finally, a system which provides super performance which was designed for wireless mobile, not VOIP of cellular which you will soon learn is the wrong way to go.

Simply put, VOIP over mobile is using GSM data bandwidth, and if you go to the fine print of TMobile or AT&T which offer optional data plans for $40.00 on top of your plan, you will find out VOIP is not permitted on their netowrk, so beware of big charges if you use any of the deals like FDII, Zero1 or Traverus, or you will be sorry.
