PPK Base Connection

So I have 3 PPK Base units (yet to be installed and setup), but I’ve noticed that someone else has a Rock PPK unit already up and running in the area. Can’t I still access that PPK unit? And would it cost me to access their PPK base?
If so, is there training on how to connect to the PPK network? If there isn’t, there should be.
