I have been a Verizon customer for nearly 20 years. For most of that time, I have stuck with Verizon because the coverage was hands down the best.
Over the last 2 years, Verizon's coverage has gotten worse and worse. I live in the north central Massachusetts. I get poor coverage at home in Groton, and now no coverage at all in the center of Townsend where I work . All the other Verizon customers at work have the same problem so it isn’t just me or my phone. One colleague switched to T mobile this week to try to get decent service. The rest of us will follow soon if we can’t get service on the Verizon network.
