I am changing Cellphone service and have to enter phone numbers in my new Cellphone. I have had several emergency numbers in my old Cellphone, which thankfully, I have never had to use. However, before I enter them in my new phone, I was just wondering what emergency numbers other people keep in their Cellphone, specifically for ON THE WATER EMERGENCIES? Where did you get the numbers? And, did you test them to make sure they work? In other words, what do you do for communications in case of an on the water emergency?

Thanks in advance for sharing,
Grumpy
