Iphone x max poor service

Keddings

6 Months ago I upgraded to the Iphone X Max. Before i did so i had no problems with dropped calls or not being able to use applications the way i should. WHen trying to make calls i get " Last Call Avalible" before getting that i can make a call for 10 seconds beofre i can no longer here and the other party cannot either

I know the importance of having a device you can rely on. I apologize for the experience. Does this affect every call or just at random? Is this happening in a specific location or everywhere? What is the current selection under Settings>Cellular>Cellular Data Options>Enable LTE? YaleK_VZW
