    Difference between USIM and SIM cards?

    Is there any difference between USIM and SIM cards? I want to buy a phone from Japan (it's a Softbank 705sh), and the description says that it can use USIM cards. Does this mean that it can use the SIM card too in Canada (from Rogers)?

    I "THINK" that is can be used in a dual ring system. For example, in the middle east alot of car telephones are using the same telephone number as the main cell phone used by the owner. Each time a call comes in and the car is running, both the users cell phone and car phone ring. IIRC the usim goes into the car phone, not the main phone, and regular sim goes into the cellular phone.

    USIM can be used for more than just phone ID like a SIM card. The USIM slot in my Samsung SCH M600 (SK Telecom) has a Shin Han Bank USIM card which allows me to access my bank account, pay bills, transfer money and so on from anywhere in the country.

    KTF is launching a USIM for purchasing KTX (high speed rail) tickets.

    SIM is a single purpose card for phone ID. USIM can be used for many purposes.

    I have a Rogers USIM. They hold 400 numbers, you can also finally hold up to 3 phone numbers per sim entry, and one e-mail address.
