mmwave 5g has some incredibly low latency compared to 4g. You'd be surprised how much of your latency is just from you to the tower.
Right now when it's not busy mmwave 5g doing a speed test I have 45ms latency and 3ms of jitter. 4g is 54ms with 12ms of jitter. When the network is loaded there's a HUGE difference. 5g can handle so many more people at once so your latency is never really that high. But when 4g is loaded down latency gets huge fast.
Ping from china to me in the US is sub 250ms on my wired internet connection so that's not really the problem. The rest is whoever is doing your phone call.
mmWave is fine when you are out in the open but anything blocking your view basically kills the signal strength. So things like stadiums and highly trafficked streets are great for it but definitely not in a building.
The mid band 5g I'm on (Mint aka T-Mobile) has little issue hitting 500Mbps here in my house.
US2CHN? 250? Wow.
My shithole has sub 100 playing local servers when wired, and moreso when playing on EU servers, something like 2-4 whole seconds when I accidentially lobbied with people writing in hieroglyphics. All these crappy old wires from early two thousands and a lack of maintainance.
But I guess, that isn't a problem elsewhere, and we'd both benefit from 5G based on your observation.
