Mobile Data Issues OnePlus 7Pro 5g

[DioOmicida]

I have the OnePlus 7Pro 5g on a Sprint plan in the US.
A week ago I noticed my phone having issues using mobile data. Speedtest.net readings always fell between .01-.2 and sometimes up to 5mbps if I am lucky.

Sprint did a speed test for me from their end and it read about 5 as well. No matter the settings adjusted or the phone being reset, nothing seemed to fix the connection issues.
Employees both at the repair center and the store clerks couldn't fix the problem. I had the phone replaced with another model assuming the issue was with the network antenna inside the phone.
However, the new phone is showing the same exact readings. It's still having mobile data issues.

Note: The phone shows full bars LTE and even 5G when in the city.

Any thoughts?
Thanks

Sprints network is shit. Was with them for 4 years, and I want those 4 years back.
