There is no mention of whether the purchaser is a purchaser, and when the usage fee is exhausted or a new communication card is purchased online and the communication card information needs to be changed, eventually it is necessary to go to the communication card sales store again. There is no mention. In addition, when using most communication cards, it is not necessary to send a communication card number, etc. every time, it is necessary to send a card number or various information by pressing a predetermined number key or a function button for each connection presented by the above device. It is difficult to judge.

An object of the present invention for solving the above problems, and relates to the automatic dial method and function using a mobile phone external device, every time the card number or various information of the purchased communication card is registered only once through the exchange system of an affiliated company Since there is no need to re-enter, the method of dispensing a card number or the like and the device accordingly become unnecessary.

Therefore, even when purchasing various new communication cards anytime, anywhere using the automatic dial method and function using the external device of the present invention, the mobile phone user was immediately considered to be able to easily change and store the unique access number, and the present invention. Another object of the purpose is to provide a method and function that can quickly and conveniently use the communication card and various communication information through the automatic dial method.

In order to achieve the above objects, the automatic dial method and function using the mobile phone external access device according to the present invention will be described in detail with reference to the accompanying drawings. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

1 is a schematic diagram of an overall communication system showing the flow of a communication system of a cellular phone. The cellular phone 100 equipped with an external access device automatically dials a unique access number 101 to use a communication card after passing through a base station. It is preferable to be configured to select one of a method of connecting to a separate telecommunication company switching center 102 and a communication method of making a general connection 105 in use of a typical mobile phone to which a charge of a mobile carrier is applied.

With the method and function of automatic dial using the mobile phone external connection device according to the present invention, Figure 3 is a comparative diagram showing an embodiment of the conventional connection method when a mobile phone user uses a communication card of a separate telecommunications company as a mobile phone If you dial only the other party's telephone number without dialing the unique access number, the external access device 4 automatically connects to the switchboard 102 of the telecommunications company, and the other party's phone number after connecting with the telecommunications company switch 102. You can make a phone call with the other party by sending the message immediately.

FIG. 2 is a flowchart illustrating a method and a function of an automatic dial using a mobile phone external connection device according to the present invention. FIG. 4 is a connector connected to the external connection device 4 when the mobile phone 1 of FIG. 4 is turned on.
