One account. Anywhere.

A registered participant can use this wireless network (wherever it is available) using a single user account. Account management is done by home (set up) organization. Using roaming is simple, a properly configured subscriber device connects automatically when the eduroam network is available. It works in the same way as connecting to foreign networks of mobile operators in roaming. From here also comes the acronym: education roaming.

The service is free for all participants.
