No, this is a common myth and there were even false emails being circulated, claiming they were from the NSW Ambulance Service, but were in fact fraudulent. See NSW Ambulance media release on 17th January 2008 on their web site: www.ambulance.nsw.gov.au

ALSO, note that most modern phones have locks and passwords on them - therefore no information can be accessed without the pin code.

ICE emails not from Ambulance.
There is an unauthorised email using the Ambulance Service of NSW name being sent around asking people to join the In Case of Emergency (ICE) campaign using their mobile phones. This email is not from the Ambulance Service of NSW. The Ambulance view on the ICE campaign is as follows:

The Ambulance Service has not launched any campaign supporting ICE (In Case of Emergency). Ambulance supports any method of contacting family in a critical medical emergency. Methods that can be used include information in diaries, wallets, drivers' licences, and mobile phones. The concept of ICE has merit and would be another source of information to assist with identification.

IT IS IMPORTANT TO NOTE: in cases involving more than one patient or a where a mobile phone has been borrowed from someone else, it may be difficult to confidently match personal belongings to any one individual. This may in turn lead to unnecessary distress. The Ambulance Service also advises that as with all stored personal information, individuals need to be mindful of confidentiality issues.
