The HTC Evo 4G is an Android smartphone that must be activated before it can access voice and data services on Sprint's 3G and 4G wireless networks. If your Evo 4G is unactivated, you can clear all the data off the phone and reset its settings to their factory default states. After you reset your Evo 4G, it will attempt to connect to Sprint's network and activate itself.
