All you have to do is have a wireless hotspot device like a Clearwire iSpot. Connect to it through Wi-Fi and place videocalls or Skype/Fring (dirt cheap minutes) calls over 3G/4G, since it now has a built-in microphone. No contracts and it can cost as low as $30 per month. The only drawback is the hotspot devices only last 4 hours, so you only get 4 hours of calling and 3G/4G browsing per charge. This is probably obvious but a new revelation.
