Service in the Michigan Thumb region

[Caldavien]

I live in Michigan and travel often to the Thumb region of the lower peninsula. Visibles coverage map show coverage in that area but I get nothing. I would expect slow or even no data but I get no calls or text. "emergency calls only". I'm using a google pixel 6 which has worked flawlessly every where else. Does any one have a suggestion for getting service in this area?

I have a family member who was in north central Wisconsin a few months back and coverage was very spotty although Visible shows the area covered and when I had Verizon I always had a signal.
