Abstract: A method of selecting a Subscriber Identity Module (SIM) in a portable terminal on which multiple SIMs are capable of being mounted, includes determining whether an application/service that is currently being executed is an application or a service for which security is previously set, selecting a SIM that is previously set for security use or a SIM that is set for general use, according to a result of the determination, and performing communication.

Abstract: A device and method for transmitting data can conveniently perform data transmission between two portable terminals. The device preferably includes a first portable terminal transmitting data on which a drag operation has occurred to a second portable terminal when the second portable terminal is coupled to the first portable terminal using a time and a moving speed of the drag operation when the drag operation occurs from the first terminal to the second portable terminal. The second portable terminal receives the data from the first portable terminal using the time and the moving speed of the drag operation when the drag operation occurs from the first portable terminal to the second portable terminal coupled to the first portable terminal through near field communication.

Abstract: A method for performing speed dialing using symbols in a communication terminal having a touch pad is disclosed. The method comprises registering a symbol in association with a phone number; comparing a symbol input by a user from the touch pad with the registered symbol; and reading, when the input symbol is identical to the registered symbol, said phone number registered in associated with the registered symbol and automatically dialing the read phone number. An error message, or a re-input request message, is displayed when the input symbol is not identical to a registered symbol.
