Please introduce the SMS function of Nokia 7500.

The short message function is adjusted to be more humanized. 7500 integrates the editing of SMS and MMS, and ordinary SMS only needs to be entered in the text editing field. If users want to edit MMS, they can easily do so by adding multimedia files. After the 7500 sends the information, the system will automatically exit the information editing interface. Unlike the previous Nokia models such as 6300, users need to close the information editing interface themselves, which is more convenient and user-friendly.
