AT&T in Indian Creek

This question has been asked before but the last response was from 2011. AT&T claims to have voice coverage in Indian Creek (no data), can anyone confirm this?

Only place I get it is at the Beef Basin pullout standing on top of my car. I get 4G with the iPhone (nice to check on the weather with all this crazy rain we've been having). Worth noting: my brother has AT&T with a different phone and was unable to acquire service at this location.

Thanks!
