Who I have the same questioned this topic

I want to know why I pay more for the highest unlimited plan if Verizon can't even deliver a reliable internet signal with 4 bars of LTE? I am literally less than a mile from the cell tower in Frisco, Tx and I have 4 bars and can't get any internet. I have had two different iPhone Xs's and my wife has an XR and none of them can get any internet without wifi at my location. I'm also on the highest plan so I know it's not a prioritization issue. What is going on?
