Sprint has dropped the prices for its mobile WiMAX service to $59.99, a $10 drop from its earlier plans. The 3G/4G plans come with unlimited data on Sprint’s 4G network and a 5Gb data cap for the use of its 3G network. Subscribers are allocated 300Mb for off-network roaming.

The reduced pricing came with the launch of Sprint’s dual-mode mobile hot spot, the Overdrive. Sprint did not issue an official statement on the cost cut and could not be reached by press time.

The operator owns a majority stake in mobile WiMAX company Clearwire, which is working to build out its 4G network to cover 120 million people by year-end 2010.
