stuck messages delete without send the data

[levomer]

At the Stock firmware I was able to read the some of the PDU of the stuck messages before delete them by the command:
echo 'AT+CMGL=1' | sudo atinout - /dev/ttyUSB2 -
But in the Custom firmware at the init of the modem the firmware delete the messages that have miss parts(some times it because the phone turn off before it get the last part of the message and not because it stuck) without option to read the PDU of the messages.
there is option that the modem will send the PDU of the stuck messages via +223344556677 before it delete them?
