...the cable or internet is down? I currently have regular, traditional basic phone service with AT&T and limited internet service (the $15 a month plan). I admit my internet service is a bit slow, but I can put up with it since I really don't download anything. I am considering switching to AT&T's unlimited cable phone service plan which would require me to upgrade a bit on my internet service (to the $25 a month plan). My biggest concern here is whether or not their ads are absolutely true that with their cable phone service, you will always be able to reach 911 service at any time...EVEN during a power outage, EVEN when the internet or cable is out, etc. In other words, that would mean that the cable phone service is as reliable as traditional phone service (which, means that the only thing that would prevent you from dialing 911 is that something unusual affects the phone line to the point that it needs to be repaired)
