Can Wickr Me users talk to Wickr Pro users?

Applies to:

Absolutely!

The Wickr Pro apps are all able to Federate (find other Users and communicate) with the Wickr Me apps, unless the Administrators of a Pro Gold Network sets up the Network for "Disabled" or "Restricted" (limited to communicating with certain Admin-set Networks).

Wickr Me, free Wickr Basic Pro, and Silver Pro Networks default to having Federation "Enabled," so users will be able to communicate with any other Me, Basic Pro, and Silver Pro users, along with any other Federated Pro Networks.

If the Pro Network you are trying to communicate with has their Federation Restricted, they will need to add your Network ID to their own dashboard under Admin Controls->Control Settings->Federation->Add ID

If the Network has Federation Disabled, you will be unable to communicate with any Pro Users on that Network.
