If the current e911 (enhanced 911) service did not exist, but you could buy e911 insurance which would allow you to reach emergency services at any time from any phone, and they would know where you are calling from. How much is such insurance worth to you on a monthly basis?
Too many variables to answer directly, but generally speaking, no. and I’m in the business.
This is not a job for insurance, this is a job for technology, which is not yet up to the task. The most you could hope for from an insurance policy would be monetary compensation if you weren’t able to get through to 911.
