I'm not following, why would we ever need +CHLD if the SIM is missing? Would we ever be able to establish multiple emergency calls to actually call this? +CHLD not working when PIN is ready and an emergency 3-way call situation is another matter though... > = > Another thing is the radio handling: making an emergency calls > requires that radio is explicitly turned on (with AT+CFUN=3D1).
