I just wanted to publicly thank all the Verizon online reps that helped fix the issue of not being able to call AT&T cell phones in the 405. Honestly, I had zero faith you could fix it after all the time I had invested with tech support and Apple tech support. I came here as a last option and had pretty much given up hope on being able to call the 405 area code.
I can't thank all of you enough. BRAVO!
