hi does anyone know if the ice is still used by emergency services? do people still have it in their phone, how about if phone has screen lock? just seen a seatbelt cover with kids ice details called icebelt wondering if I should buy it, i have a tag for my son who is diabetic but it doesn't have next of kin on it, this ice seatbelt pad does, how would ambulances know my son was diabetic if I had a crash or who to contact if I was out cold? any thoughts?
