Incorrect Band Searching Configuration for NB-IoT and Cat-M Modes After configuring the PRL(AT+KSELACQ))

Can I use AT+KSTATEV <eventc> as a network signal indicator to detect if there’s any cell around the modem, even if the SIM provider has no agreement?

What I’m trying to achieve is this: if there’s no cell or RF network signal, then switching to SIM 2 would be pointless. Since there’s no signal at all, I want to avoid unnecessary searches and save power…
