I want to change cell phone carriers. I have Sprint and get many dropped calls?

I thought it was mainly my workplace. But on the main road, in my house, etc. Sometimes my phone will overheat for about a minute, then get failed signal. I was wondering if their is a way out of my contract? Any type of cell phone lemon law? Should I write to attorney general. I was told AT&T and Verizon are good; Verizon is just very expensive, and sort of al a carte?

i have verizon & i love it. the signal is most likelt everywhere. the phones are amazing and wheever u hear about verizon its how there putting up a new tower somewhere so u know they care about service more then phones
