Again, can someone explain how free roaming works?

GSM operators are obliged to pay per-minute termination fees when their customers receive calls while connected to foreign networks.

how come IOM and Lichtenstein GSM operators are exempt from termination fees ?

is that a reciprocal agreement of no-termination-fees between these particular countries and the 60-130 countries that are listed on "free roaming" sim suppliers sites ?
