In case of emergency; data to be used for emergency contact, especially emergency contact phone number in a cell phone. This seems to be a fairly new acronym developed in an effort to define a standard title name to be used for emergency contact numbers on cell phones. It appears to be fairly new but is becoming widespread due to chain E-mails that have been circulated recommending that people create an entry in the cell phone contact list called ICE where they store a number to be called in case of an emergency. Evidence suggests the term may have been formed or at least popularized following the London train terrorist attacks in 2005.
