I have my own iphone 12 mini on a personal account, and a work iphone 8 on my employer's account. I have just moved to a new neighborhood and now they both continuously drop calls. Cell phone coverage as indicated by bars is very poor in the immediate area. I can barely make a call in my apartment, even hanging out the window. I live in a major city, San Francisco, in a central neighborhood. There is no excuse for Verizon to provide this poor a service in the supposed technologic hub of the nation, let alone at all in any metropolitan area.
