I'm thinking of replacing my series 3 watch with a series 4, mainly for the fall detection feature. My current watch is the cellular version, which I have never activated. I'm wondering which version of the 4 to get. If I get the non cellular version and suffer a fall, I assume that if my phone is in range it will dial 911. What I'm wondering is , if I buy the cellular model and don't activate it would it be able to dial 911 if my phone is out of range. I know that cell phones are supposed to be able to call 911 even if they are not connected to a carrier. thanks for any info.
