Who I have the same questioned this topic

According to the coverage map, we should have 4G service at my home. Service has been getting progressively worse and now is 3G with 1 or 2 bars or worse most of the time. We used to be able to go outside to get stronger service and now we don't get stronger service outside. I am wondering if other services are stronger in our area and I am considering exploring a new service provider. Can Verizon fix the service/coverage level in my neighborhood?
