I'm getting real frustrated with dropped calls with my cell phone. I know there are dead areas for service, but is there one that works a little better? I use it for business mostly. I was getting them with AT&T. So I switched to ALL-TEL and they are probably worse. I heard Verizon is the best for not getting as many dropped calls. Although they are more expensive, but thats ok if its better. Any opinions on the best provider?
