No really, LE910V2 does not need AT mux as far as i know - it uses
separate network interface as default (CDC-NCM).
I also tried PPP over modem port, worked ok, just switched aux and modem
ports for it to work ok.

And #QSS=2 returns right away.
First #QSS query returns 0 (SIM not inserted) but seconds later #QSS
notification arrives with status 1

Kind regards
Piotr
