Question about Cat S42

Has space for 2 Nano-Sim and Micro-SD at the same time - but is Active-Sim. I make calls and send text messages via one card and data via the other. You can also set "Ask every time" for calls and SMS.

The way I saw it in the specs, it would have to be a nano SIM, dual stand-by, mine has room for 2 sim cards.
