I own a Nexus 6P and previously owned Galaxy Nexus. Starting around a year ago, my Galaxy Nexus started having trouble reliably keeping a LTE signal. I thought it was the phone and bought a 6P. I still have the same problem. Nothing helps.
I live on the southern coast of Maine where Verizon has claimed for years to provide dependable LTE coverage and it was true for me until a year ago. I reboot, go in to and out of airplane mode, and other supposed tricks. I am on the grandfathered unlimited data plan and feel like I am being singled out, a practice which Verizon supposedly stopped. Is there another explanation?
