What means +QUSIM: 1

[Abner-Q]

@Hardy.acht

I think CEREG 2 is the start of a new “searching” and 0 is the end. But what means QUSIM: 1 for me? And why i got: +QIND: SMS DONE SMS initialization finished?

QUSIM: 1 is the identification of the SIM card type.

This information is the initialization result that the module actively returns at boot time.
