SMS Receive suddenly stopped working

[grinzie]

I can't find the thread with the specific command right now, but you can use mmcli to clear the incoming cache. I had the same problem a couple months ago, and clearing all ten slots fixed it.

Thanks for the suggestion. The problem persists (confirmed not receiving some texts).
I found the link: https://forum.pine64.org/showthread.php?tid=9687
Flushing the cache makes no difference.

    sudo mmcli -m any --command='AT+CMGD=?'

gives:
+CMGD: (0),(0-4)

    sudo mmcli -m any --command='AT+CMGD=0,4'

gives:
+CMGD: (),(0-4)

Still not receiving texts from test phone.
