Since some mentioned it in another thread; I was just curious what has been done to hopefully improve things - especially for us AT&T stuckees.
About the only way I found around it was to call someone I knew who had a non-ATT phone who could then call my wife. It seems that if AT&T saw that you were trying to call another AT&T customer on the same cell tower, they'd figure that you're close enough that you don't need to make a call. Whereas making a call to another carrier's customer would always go through. Same way in reverse.
I'm not kidding; I'd call my buddy and say, "Hey, John, could you call Betty and tell her to meet me at Twin Oaks?" We couldn't even get texts to go through.
Thanks for any info on upgrades!
