Hello, I've been somewhat following this thread and finally purchased service with OTR.
Disclaimers: I used to live in Texas but now live in Oregon and I'm full timing in an RV.
I used the discount code someone posted earlier and it still worked. I waited longer than told by OTR for my package to arrive. I bought the Velocity 2 package, which was the cheapest and this is the outcome:
At first, I had 4G and 3-4 bars out of 6 I think, and I was getting horrible speeds and latency jitter, so I talked to OTR like several people mentioned and told them this, and he did something which slightly improved my service. I was getting about 60-120ms ping, with 120 being the upper jitter and 375KB/s average speeds. I frequently play competitive counter strike, so this is acceptable compared to my current WISP at the RV park, and keep in mind that this is with absolutely no line of sight, with loads of thick trees and a literal mountain in the way of the Velocity 2.
After playing for a couple hours, I do another speed test to be amazed at about 3MB/s max, with 1.8MB/s being the lowest (about 25Mbits max), but I noticed I am getting a single bar but my Velocity is now saying 4G LTE, making me think I switched towers at some point.
This is still day one, I don't know that I will remember to come back to this to post my results later down the line, but I am very happy with this currently, as my latency has stabilized to about 60ms. I will be trying to pinpoint where this LTE tower is, as it is not the one I had originally thought I would be connected to and I will buy some high gain Antennas because this thing has two connections.
I just wanted to say thanks to the people on this forum for all of the information and to give my own information. This is a huge improvement from the RV park internet, which uses a WISP which has INSANE packet loss, and the park itself limits my connection to 3Mbit speeds.
If anyone has any questions, I don't know if I will be alerted by a response to my email, so I will try to remember to check this page every now and then for a response.
