I work in 85613, Fort Huachuca and the Verizon cell tower that services us has gone from multiple 3-10Mbit of bandwidth (around February-March 2016) and has since dropped down to sub 0.5Mbit. I have driven around the area and even within a couple hundred feet of the tower and the bandwidth remains the same no matter how strong the signal bars indicate. This is only a problem with the tower on Fort Huachuca, as soon as I drive 2mi into Sierra Vista 85635, I pick up the next tower and speeds return to 3-10MBit.
I even went to the Verizon store and they replaced the SIM on my iPhone SE and there was no change in performance.
Please help!
