Controlling the size of attachments that users can receive on their
BlackBerry devices
By default, the BlackBerry® Attachment Service in the BlackBerry® Professional Software does not limit the file size of an
attachment that is embedded in a message or retrieved through a link . The BlackBerry Professional Software sends data to
the BlackBerry device in packets that are no larger than 64 KB; however, the BlackBerry Professional Software can send an
unlimited number of packets.
To control attachment file size, you can specify a maximum file size for attachments. You can also configure the maximum
dimension for images.
