Where in my post did I suggest that you should switch your carrier? I merely told my story which is that bad cell signal gave me terrible battery and suggested that people who don't understand why their battery is draining so quickly to keep an eye on their cell signal to see if that's the problem. If that's the problem and they find it, then what they decide to do with it is their own problem. I fortunately am in a country at the moment where I can change carriers like underwear, and I'm sure there are other countries where you can do that as well. Just because you're stuck in the States where carrier companies control your phone doesn't mean other people suffer the same fate.
I am tied to at&t when I return to the States, but luckily the reception in my area is great, so no need to change for me
