The Queen of SIMs [mobile phones]

The SIM (Subscriber Identity Module) transformed the smartcard business as mobile phones started to flourish and each had to carry one. But, as the networks become increasingly complex, offering a multiplicity of capabilities to the users-multimedia applications, high-performance processing, large storage and commerce-the complexity of the SIM grows, too. The USIM (Universal Subscriber Identity Module) will improve the relationship with the users and it's a good candidate to enable content delivery. The USIM is expected to offer higher capacities, going into the megabyte domain, to be able to store even more data to meet the growing number of applications in its pitch to be 'all things to all people'.
