T-Mobile 5g internet upload just 15mbps? Seems Slow. Is this normal on other networks AT&T, Verizon?

Is it normal for the upload speeds for 5g to be slow? In Orange,California... the speed is slower then when I used LTE on an older iphone??
I tested with an iphone 13 pro.
Download speeds were great at 300+mbps.
But upload speeds were not great... just around 15mbps...
Is this normal to have such slow upload speeds. If you have ATT or Verizon is this normal?

Not all but alot of tmobile 5G towers especially those that got the upgrade before 2022 only handle download, and just use LTE for upload which is why your upload speed is about the same as LTE. It's also why tmobile tends to have higher latency, but also faster download then Verizon and AT&T

Thanks for the clarification. Makes me wonder if home wireless internet would have the same speeds.
