No Internet at one Location


There is a location that I visit routinely (1030 South Coit Rd 
Prosper TX 75078
Where I cannot get any internet in & outside the office. All other services (voice & text messages) work. I'm on Visible + and an iPhone 13. It shows 2 bars signal strength & 5GUW. I can get internet with the same signal strength in places about 200 feet from this location. I was hoping that moving to Visible + & the 5G phone would fix the problem. But no joy. Could there be something wrong with the way this tower handles Visible + data? I realize that cell service can be strange, but I've never encountered this situation of a signal but no internet. (I also tried LTE - same result.)
