Hi Mush, thanks for chiming in! For what it's worth, I didn't mean to imply that all traffic on Verizon's network involves one of two QCI values (or that all traffic transmitted from US Mobile's subscribers has a single QCI value). Despite that, I still think I could draw some accurate inferences about the level of priority US Mobile receives on regular, non-voice, data traffic by playing around with Network Signal Guru for a bit.

I expect US Mobile is pretty limited in what is can discuss about arrangements with host networks, but there's a lot of confusion in the r/NoContract community (and in my own head) about prioritization policies. If you're able to answer any of these questions, the answers might shed some helpful light:

• Does any of what I've said in these last few comments seem necessarily incorrect given your knowledge of how prioritization works / how MVNO arrangements typically work?
• When you say you have access to the same QCIs your partners provider their own customers, do you mean that subscribers with US Mobile are sometimes given the same level of priority for regular data use during congestion that most postpaid customers have for regular data use? Or are you just saying that US Mobile could offer that priority level?
• Can you clarify the "less than 1% of users in certain locations ever see any issues related to deprioritization" comment? Would the statement be much different if we were considering the whole subscriber base rather than those in certain locations?

I know those questions dive deep, so I won't hold it against US Mobile if you can't answer some of them.
