It would appear not: the docs [BGS2 & EHS5] define +CSIM as always requiring two parameters (length,command).
I tried the rest of the Telit +CSIM's and they can sometimes work without any other. Albeit with some other quirks as to which work on which modem and when.... not yet had a chance to fully capture all the behaviour on both modems; but they don't seem to need unlock/lock.
