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.

I always use a VPN when on the hospital's wifi for the same reason. Everything works so much better.
