In response to a user input for attaching at least one file to a message to be transmitted using a messaging application, in operation S611, the electronic device may determine whether the message can be transmitted based on the RCS. For example, the electronic device may receive information (eg, a phone number or user account) for identifying a recipient who will receive the message, and an external electronic device of the identified recipient based on the received information transmits the RCS message. It can be determined whether or not it can be received.

If it is determined that the RCS message can be transmitted to the external electronic device, in operation S613, the electronic device may determine whether the format of the selected file is a file format supported by the RCS standard. For example, when the format of the selected file is the APK file format, the electronic device may determine that it is a file format that cannot be transmitted through the RCS message. When the format of the selected file is not included in the file format supported by the RCS standard, the electronic device may perform operation S619. When the format of the selected file is included in the file format supported by the RCS standard, the electronic device may determine whether the original of the selected file can be transmitted in operation S615. For example, if the size of the selected file is less than or equal to a specified value (eg, 20 MB, 100 MB), the electronic device may determine that the original can be transmitted, and if the size of the selected file exceeds the specified value, it may determine that the original cannot be transmitted. . If it is determined in operation S615 that the original of the selected file cannot be transmitted, the electronic device may perform operation S619.

Capacity limits may be set for In operation S619, the electronic device may determine whether the selected at least one file is within a capacity limit range. When it is determined that the capacity of the selected at least one file can be transmitted based on the link transmission function, in operation S621, the electronic device may generate link information and insert the link information into the message. The electronic device may upload at least one file to the server so that the at least one file can be downloaded using the link information.

According to various embodiments, when it is determined that at least one file selected in operation S619 cannot be transmitted through the link sharing function (eg, when it is determined that the capacity limit is exceeded), a function other than the link transmission function is used. A process for transferring the selected at least one file may be executed. For example, if it is determined that the available capacity on the day is exceeded when transmitting at least one selected file, the electronic device informs that the capacity of the link transmission function has been exceeded and a notification message suggesting another process for transmitting the file can be displayed. The other process may be, for example, a process of changing the size of at least one file and transmitting it, or a process of transmitting it by trimming it. In response to a user input for agreeing to another proposed process, the electronic device may transmit the selected at least one file by performing another process.

If it is determined in operation S611 that the message cannot be transmitted to the external electronic device based on the RCS, in operation S631, the electronic device may determine whether the format of the at least one selected file is a file format supported by the MMS. For example, when the at least one file format is a multimedia file, the electronic device may determine that the at least one file can be transmitted based on the MMS. When it is determined that the format of the at least one selected file is not a file format supported by MMS, the electronic device may perform operation S637. When it is determined that the format of the at least one selected file is a file format supported by the MMS, it may be determined whether the original of the at least one selected file can be transmitted in operation S633. For example, when the capacity of at least one file is less than or equal to a specified value (eg, 300 KB, 1.2 MB), the electronic device may determine that the original can be transmitted. When it is determined that the original of the at least one file can be transmitted, the electronic device may attach the at least one file to a message to be transmitted based on MMS in operation S635. When it is determined that the original of at least one file cannot be transmitted, the electronic device may perform operation S637.

In operation S637, the electronic device may determine whether at least one selected file can be transmitted based on the link transmission function. For example, in operation S637, the electronic device may determine whether the selected at least one file is within a capacity limit range. When it is determined that the capacity of the selected at least one file can be transmitted based on the link transmission function, in operation S639, the electronic device may generate link information and insert the link information into the message. The electronic device may upload at least one file to the server so that the at least one file can be downloaded using the link information.

According to various embodiments, when it is determined that the at least one file selected in operation S637 cannot be transmitted through the link sharing function (eg, it is determined that the capacity limit is exceeded), a function other than the link transmission function is used. A process for transferring the selected at least one file may be executed. For example, if it is determined that the available capacity on the day is exceeded when transmitting at least one selected file, the electronic device informs that the capacity of the link transmission function has been exceeded and a notification message suggesting another process for transmitting the file can be displayed. The other process may be, for example, a process of changing the size of at least one file and transmitting it, or a process of transmitting it by trimming it. In response to a user input for agreeing to another proposed process, the electronic device may transmit the selected at least one file by performing another process.

In operation S641, the electronic device may transmit a message to which link information is inserted or a message to which at least one file is attached in operation S617, operation S621, operation S635, or operation S639.
