Posted in: GSM News | April 28th, 2009
KTF from Korea researched and brought to life the first functional USIM prototype with 256Mb and 512Mb. Now they are working on a 1Gb USIM.
For those that don’t know what USIM is…
Definition USIM : SIM cards (Subscriber Identity Module) are used to communicate on GSM networks. With the introduction of UMTS or 3G, it is necessary to use a USIM (Universal Subscriber Identity Module) or 3G SIM card. Although it is possible to use a USIM card on a GSM mobile phone, it is impossible to access UMTS network services using a simple SIM card. A 3G (UMTS) handset equipped with a USIM card can be used to make video calls, assuming the calling area is covered by a 3G network.
