I just moved to Evergreen and am anticipating getting some half work/half board days in. But to do so, I'm going to need to be able to check an email here or there on the lifts or take a call at the base. I currently have Verizon, and got no service at A Basin last year. I also had no service in the Outback at Keystone. The Keystone dead zone was a big issue because my kiddo takes lessons there and they want to be able to call you if they need to ask you a question.
So....please let me know if you have a cell provider that works in these areas. I know AT&T works at A Basin, but don't know about the Outback at Keystone.
For what its worth, Verizon has been solid at Breck, Vail and Beaver for me.
Thanks for all the help!
