In addition, when the message to be transmitted is long, the service fee is increased as the user divides the circuit into multiple circuits and transmits them. In addition, after sending a message, the other party cannot confirm whether the corresponding message is received correctly and thus cannot guarantee the reliability of the message transmission.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and allows a wireless terminal to download a program capable of processing a message having a large size of 500 bytes or more, and sends a message written using the same to a desired counterpart using a data communication method. There is a technical problem to provide a message service providing system and method for a wireless terminal that can transmit a message of more sufficient content by transmitting.

Another technical problem of the present invention is to provide a message service for a wireless terminal capable of ensuring compatibility and reliability of message transmission under any conditions by dividing, processing, and transmitting a short message in a situation where a large size message cannot be received. It is to provide a providing system and method.

Another technical problem of the present invention is to notify a message sender of a service result after completing a message transmission service so that a message sender can check his or her message transmission details.

In addition, the present invention has a technical problem to reduce the service usage burden of the user by charging a low service fee for the transmission of a large size message by transmitting and charging a large sized message in packet units.
