The HTC Bolt speeds are supported by Sprint’s advanced network and the integrated Snapdragon X10 LTE modem, which incorporates LTE Advanced with 3X20 MHz Carrier Aggregation. Category 9 download speeds can reach up to 450 Mbps, thanks to the X10 LTE modem’s ability to connect to LTE networks, engineered to use up to three full-bandwidth LTE connections simultaneously. By taking advantage of these connections, data rates are increased and network response times are faster, which means less internet lag and speedier downloads.
