   I can't find it documented anywhere. The closest I have is this:

NOTE:	Commands which interact with MT that are accepted when MT is pending
	(emergency call), +CPAS, +CFUN, +CPIN, +CDIS (read and test command only),
	and +CIND (read and test command only).

   Observed behaviour of the Calypso GSM modem is that +CFUN=1 to turn on
transmitter and receiver is rejected when the SIM slot is empty. But it
seems likely that emergency calls are allowed through by the modem even with
no SIM card in it if you go straight to the D112; command.

   Btw, who wants to bet on the existance of some silly phone app which will
refuse to dial 112 if it can't register to a network?
