I recent found that I am unable to dial 911 from my phone. I am on the road a lot, and seem to happen upon recent accidents more than the average person. I have found that I am unable to dail 911. I am usually in areas with service, and have found that I can call the non-emergency lines without any problem. however if I dial 911, the call does not connect. Instead I get an error. I have also grabbed someone else's (also ATT) phone and been able to make the 911 call.
