NetZero took a different direction Monday by starting up its own 4G service. Its Clearwire-sourced WiMAX is contract-free and has the unique choice of picking either a basic (1Mbps/384Kbps) or full-speed (10Mbps/1.5Mbps) access plan, even having the option to switch over the web. The service also lives up to the company's once historic practice of offering service: those who buy a modem can get 200MB of data each month for free for a year, with the device price already covering the cost.
