Wr havr a local course that is on a new housing development.
There are a lot of dead zones where you can text, but calls are dropped immediately.
You have to stand on a hill at the top of the course for reception .
Also, no service for internet on phones.
Unless you drive close to a house .
It will say 'Bob's wifi is available. Get password and sign in for use '
I'm wondering if they planned this.
