Over here (Finland, EU) there used to be standardisation that a mobile phone must be able to make an emergency call even when the phone is locked, and even when the phone's own carrier is out of coverage, or when there is no SIM card - the call must be routed as a guest in any GSM network that is there. That may now have changed, because the user instructions for iPhone say (translation mine): "iPhone can be used to make emergency calls in many locations, if mobile services are available, but you should not trust on it in cases of emergency". Yes, apparently iPhone user instructions say that when you're in an emergency, don't count on iPhone. You should carry a phone with you in addition to iPhone. When dialing 112, the phone goes to a special mode: the call is prioritised (if the cell is full, another call is dropped) and if carrier's network is not there, the phone tries any other network. (I've seen this work on my phone, but that time it didn't help, the guy died.)
