How to sort or list received "UNREAD" SMS messages

Oh, I see now...

Use AT+CMGR=, and just list all indexes.
And delete that index as soon as PIC receive whole MSG.
Also you can use AT+CMGL="ALL",1 to not change status...

Look at 4.2.3 AT+CMGL and 4.2.4 AT+CMGR

Also you can use AT+CMGL="ALL",1 to not change status...

Okay, this is new to me.

I'll give it a try right now - thanks a lot

Look at EDIT in prev. post.
But I prefer described way, to list index one by one, and when pic receive MSG delete.
Do this one per second, and I cant have more than 1 or 2 unread msg. And then it is easy to get correct order, and everything else.
I have done that in past, if I can remember...

Well, the AT+CMGL="ALL",1 doesn't exist (at least not for the SIM7600E module).
