I had to switch carriers because of the same reason. Even though I still don't get service here at home, at least when I'm out of the road traveling I have some form of communication if anything goes wrong.I cancelled my cell phone that would only work when I left the boondocks and generally then, I forgot to take the phone. LOL
I had the same carrier for almost 12 years, but went with TracPhone a few years back because you can pay as you go. Some kind of promotion at the time I switched over gives me triple minutes and user time for life. I also don't use the internet/web or text on it. I can buy a 30 day card for around 20 bucks or so and it automatically gives me 90 days, plus more minutes than I've ever been able to use up. I saved a bundle of money and got to keep my same cell number too.
$90.00 dollars or less a year as opposed to over well over $600? It wasn't a hard decision to make for as little as I ever use my cell.
