should be specified. As a result, different attachments should have different file index. The maximum
number of attachments is 10.
The attachments can be RAM, UFS or SD files (RAM files are strongly recommended). Files can be
uploaded to RAM, UFS or SD card by AT+QFUPL. After sending the email successfully, the files in RAM,
UFS or SD card should be deleted by AT+QFDEL. For more details of these commands, please refer to
Quectel_EC2x&EG9x&EM05_FILE_AT_Commands_Manual. The mail service provider may have some
