Here is my history.
iPhone6, various data plans 4G-16G speeds were acceptable from all phones on plan.
upgraded to Pixel2, yesterday and also changed plan to GoUnlimited. Speeds using fast.com, speedtest.net, and verizon.com/speedtest were all 1Mbps or less
last night I changed my plan to BeyondUnlimited. Now I am getting
fast.com - 5-6.5Mbps
speedtest.net - 12-22Mbps
verizon.com/speedtest - 30Mbps
Interestingly I am also getting better 4G LTE coverage than I was yesterday.
I just did a side by side test with a co-worker who has TMobile. His test using verizon.com/speedtest was 108Mbps!!!!!
Something is really wrong here and it needs to be fixed.
