Thatvyou have to ask the manufacturer. Its not a Traccar thing
I don't think it can be done via SMS - it may be possible to do it via a serial (wired) connection.
You'd want to check the value of Parameter 770 - "Accumulator Reporting – Accumulator Count by Event Code" that's the only thing I can see that comes close.

Hello Support,
Is there an SMS command that tells the number of events waiting to be sent stored in the Calamp device?
Thank you.
