The max speed of 3G is estimated to be around 2 Mbps for non-moving devices and 384 Kbps in moving vehicles. The theoretical max speed for HSPA+ is 21.6 Mbps.3G service, also known as third-generation service, is high-speed access to data and voice services, made possible by the use of a 3G network. A 3G network is a high-speed mobile broadband network, offering data speeds of at least 144 kilobits per second (Kbps).
