AT^SISS=0,lastWillQos Poblems | Thales IoT Developer Community

I'm working with the Cinterion module ESX82.
When I use the commands AT^SISS=0,lastWillQos,"2" and AT^SISS=0,lastWillRetain,"1", I have the follow error message:
+CME ERROR: operation failed
What could be the reason? Is my command syntax wrong?
Thanks and Regards,
