Maximum data transfer rates of UMFS is 42 Mbits.

Objective behind UMTS

2g and 2.5G systems are incompatible with advanced technologies and provides less data. These systems are enhanced with new features to design a UMTS system, which is capable of working across world with high data speed i.e. 2048Kbps.
