I've spent nearly $500 in early termination fees and other carrier's bills over the past year TRYING to leave AT&T.
Their service is absolute horse sh|t in Houston, particularly in the medical center. I work at a hospital where I can get in an elevator in the basement with a person talking on a Verizon, Tmobile, Sprint, and a Cricket phone and ride all the way to the 12th floor and they never miss a syllable.
Me? Not only do I not even have a single bar in the basement, I don't have a single bar on the top floor either. There are about two places I can think of in the hospital where you will always find AT&T customers (doctors and patients alike) huddled with their heads cocked next to a window trying to get reception.
So I've tried to leave...multiple times. The iPhone and AT&T makeup the worst possible "phone" that has existed since the early 90s. Problem is that the iPhone is the greatest gadget that has ever been created and I simply am unable to give it up. And, even sadder, the iPhone would become the greatest "cell phone" ever made if it would just be on a good network like Verizon.
So...all in all...at work, I now have a $19 Verizon pay-as-you-go phone that works flawlessly everywhere around town. I then have my iPhone to do everything else...just don't count on it to make or keep a call.
