My voice coverage on Sprint is unacceptable at home and at the places I frequent. This is true whether using a flip phone or a smart phone. Both phones allow roaming, as does my plan. Can I assume that Verizon voice coverage would be equally unacceptable in these areas? If not, why not. I'd like to understand. Data coverage is no better but my main priority is getting a phone/network that will make phone calls when I need it to.
