I have a fun story about using Warp while on vacation (Bahamas). I was finding that my net traffic felt like it was slower/more variable than I'd expect with uneven speedups and slowdowns.
On a whim I installed and turned on Warp and suddenly my internet speed was both palpably faster and more consistent in its speed. I think it possible that one of the side effects of encrypting your traffic may be that it evades ISP traffic shaping.
Back when I used Visible (North American MVNO) for my phone, you could get substantially faster speeds and less latency by enabling Warp because it bypassed their traffic shaping and limited egress points, for example if you viewed Netflix without Warp you were throttled to 480p but with Warp you could easily do 1080p.
I had a similar experience. Higher resolution netflix on my T-Mobile prepaid data line with warp installed.
Additionally I did the bog standard TTL modification, installed warp and probably one or two other things I can't recall. For whatever reason those changes allowed me to tether unlimited 4G speed data rather than being throttled down to 3G after a few gigs. This was true for T-Mobile, US Mobile's "verizon" tower mvno service as well as US Mobile's "t-mobile" tower mvno service. Can't say I was upset about it.
