T-Mobile has a new achievement with its Ultra Capacity 5G. The Un-carrier recently announced that it had achieved its goal to cover 300 million people with 5G UC. The best part is that this was achieved months ahead of schedule since the goal was to achieve this by the end of the year. Thanks ...
You're on Google Fi, so that's not real. You realize being with an MVNO means you're de-priorotized on the network right?
That said, even with that being the case something's very wrong there and should be addressed, but that's in no way a representation of 5G UC, 5G or even LTE or 4G.
I'd download a network analyzer and see what network you're actually being physically connected to and start troubleshooting from there. Google Fi uses TMO in most areas, find a person that's actually a TMO customer and see what their speeds are.
