If an EMT or paramedic is busy saving your life, they will NOT have time to check ICE or call anyone on your cell phone. Also, some phones are "locked", especially the smart phones. EMTs DO check your wallet, so keep a card with your "ICE" contacts there, along with brief medical history - especially allergies and what meds you are on. Police officers will sometimes check cell phones, but please don't count on this a being a "life saving" measure. This comes from a Boston paramedic who has 8 years in the field. Hope this clarifies things...your wallet or pocketbook is your best ICE tool!
