BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone terminal and an e-mail creation method, and more particularly to a mobile phone terminal having an e-mail transmission / reception function such as a mobile phone and an e-mail system using the same.
[0002]
[Prior art]
In recent years, with the rapid spread of information terminals such as mobile phones, personal digital assistants (PDAs), personal computers (PCs), etc., electronic mail transmission / reception using communication networks has been actively performed between these information terminals. I came. In mobile phone terminals such as mobile phones, various services are provided by each business operator, one of which is a service that can use electronic mail.
[0003]
If e-mail is used, it is possible to send and receive e-mails even if the providers of the mobile phone terminals on the sending side and the receiving side are different.
[0004]
[Problems to be solved by the invention]
However, the number of characters that can be transmitted / received in an e-mail of a mobile phone is limited, and the limit differs for each mobile phone carrier. Therefore, when sending an e-mail, it is necessary to create an e-mail considering the number of characters that can be sent and the number of characters that the other party can receive. Because there is no means to know, when creating an email, it is common to create an email according to the maximum number of characters specified by the carrier of your mobile phone, and send the email exceeding the maximum number of characters received by the other party In such a case, there is a problem that the contents are not transmitted to the other party, or that the screen needs to be scrolled to display a part of the mail that cannot be displayed on the display screen on the receiving side.
[0005]
Therefore, in a conventional mobile phone terminal, information (terminal information) related to a communication device used by the transmission partner is stored in a storage unit in association with the mail address of the transmission partner, and the size and display of the display screen are displayed.
