So, sounds like you should be on the right track.
However, in my experience, the first tier support is usually not always the most informed. Their primary task is to get rid of as many customer questions as possible to prevent things from being escalated to the more costly higher tier support.
You have some good questions that probably are not going to get a proper answer on a hobbyist website. I think you'd be better off working on getting the ticket escalated within Verizon. Present your findings and ask for a explanation as to what you are seeing. It's entirely possible your phone was not properly set up, could be a local issue with the cell site, could be any number of things. Until you get the right set of eyes on the issue, you'll continue to get brushed off by tier 1 support.
i'll post below their response from yesterday's email. You're right, they should have all the answers, but last month when i starting inquring, I was sure getting the run around! I've bugged the **** out of them for it too. Different answers to the same questions has done nothing but provide me with some entertainment during downtime at work! I'm going to do a little field test this weekend at the major event i was talking about previously. Might even take a First Net company phone with me to compare results. I'm really not expecting my phone to work this weekend at the peak of the event just like last year, but we'll see!!
"Subject: Network Speed Expectations for First Responders
Hello:
I have a question about network speed expectations for first responders with Wireless Priority Service. I have been told that Verizon automatically adds Priority Data to my device when enrolled in Wireless Priority Service. I live in a college town in which the LTE network is consistently saturated during the day and into the late evening hours. My download speeds are often as low as 2mbps during the day and late evening even though I have full signal and am not over my 22gb high speed allowance. I have conducted several speed tests simultaneously with friends that also have Verizon iPhones but without priority features. Their network speeds are the same as mine, and sometimes even faster. The tests have all been performed at the same time, in the same location, from the same speedtest source. Please help me to understand the dynamics of Always On Data Priority. Should I be expecting a minimal LTE download/upload speeds? Can you further explain in detail the true meaning of Priority Data, particularly what kind of speeds I can expect on a congested network? Is network speed even a reliable test for priority data? I don't expect full LTE speeds, however I do expect the speeds to be fast enough for me to use basic apps such as the Maps App and basic Safari webpages, but perhaps my expectations are skewed.
Thanks so much for your help,
Matthew Ervin"
"Hello Matthew,
We have received your inquiry.
The addition of the priority feature does not cause your data speeds to increase or decrease. The feature allows you to gain access to the network during heavy traffic or emergency situations when there may be little to no access to the network. Once you have access to the network, your device will operate at it's normal speed or speed that is based on your plan. Unfortunately, the feature will not increase your data speeds. It is only priority access to the network when others may not be able to access due to emergencies in the area or very heavy traffic.
In case you need it, here is your reference number: 178320367"
Still no mention of a minimal download/upload speed, so i'm still not entirely sure what "priority means". If the speeds are too low to do anything at all, it's no benefit for me.
