Seems to be an "Oreo" issue or "non-Sprint branded phone" issue (Nexus 5, 5x, 6, 6P, Pixel 1, 2, 3).
Be interesting if anyone with any of these phones can successfully 'LTE Data Roam' on USCC now...
Just found this link.
See my post from 2 months ago not being able to roam in US Cellular territory with either of my Pixel 2 XL's. This area has been rock solid previously.
175 ms pings
1200+ ms jitter
.01 Mbps upload
timeout errors
that's not "terrible"? good luck with your VOLTE phone calls.
non-network people also don't realize that when you're upload is taxed out, there goes the download speeds and pings...
Speeds and overall reliability seemed to take a step backwards with the latest firmware push for me. If anything, ping times *might* have improved when the unit actually works.
I noticed the Sprint IP too, but went by the Wifi indicator at the top. When I'm not on LTE and try to do a speedtest.net test, it connects to a Sprint server.
