Problem with high latency/ping

@dreaminggates  I don’t have an answer for you but this has been my internet experience:

I have been with T-Mobile since last October, about 3-½ months. 5G isn't available in my area to everyone so they gave me a 4G gateway. My ping was in the 30's and 40's ms. I had the gateway in the upstairs window facing the tower it's connected to less than a mile away. I only had 3 bars at best. My speed was between .25mbps and 10mbs. Averaged about 7mbs. These are not the advertised speeds and there was nothing customer service could do to get me better speeds. 

Last week T-Mobile sent me a 5G gateway that allows me to get better speeds. My average speed is around 15-20 mbs. Still not the advertised speed of 5G. Customer service says that I won't always get 5G speeds and that I would mostly be on the 4G speeds until the 5G network expands. With the new 5G gateway my ping is worse. It's around 50-60 ms ping at times. Certain online games are unplayable because the in-game ping is well over 100 ms bouncing to 400-600 ms at times. I also used TCPOptimizer, to no avail.

Even though it's sub-par service I'm thankful that I have SOME internet as it's my only choice besides satellite where I live. I think the nature of sending data over the airways lends itself to high ping. I don't have any proof but just seems to be the common complaint of T-Mobile home internet users.
