I've been experiencing extremely slow data speeds at my office in downtown Montgomery, AL since I started my job here last year. This is an ongoing problem, and my girlfriend who works a couple of blocks away has the same problem. I just upgraded to an iPhone 11 Pro. I was having the same issue with my iPhone 8. The zip code here is 36104. Speeds are much better at my house, which is in 36106. I would very much appreciate it if someone from Verizon could check the coverage here and see what the issue is. I'm posting images of two speed tests I ran this week, which are typical, one from Monday and one from today.
