Yes, I have ICE numbers in my cell phone. When you enter the contact's name and number in your cell there is an option to set that number as an ICE contact. I have 2 listed; one friend and my husband. When you look at my list of contacts the ICE numbers are red to differentiate from other numbers. I use an LG phone and my carrier is Verizon. I imagine each has slightly different software, but same idea.
