Is there phone service in the camp?

Cell service is sketchy but if you can make Wi-Fi calls you should be good at the Trading Post and I think the mess hall

Many places have no service for calling. Texting is easier in more places

Depends on your provider, att is very spotty

Yes

There's free wifi in the program center and the trading post. Cell service is sketchy everywhere else. Some carriers work better than others.

Verizon works better than AT&T, however service is generally spotty.

Verizon has the best signal in camp but there are many places where there is no signal. Camp has Wi-Fi in many of the facilities.
