Sec. 22.927  Responsibility for mobile stations.

    Mobile stations that are subscribers in good standing to a cellular 
system, when receiving service from that cellular system, are considered 
to be operating under the authorization of that cellular system. 
Cellular system licensees are responsible for exercising effective 
operational control over mobile stations receiving service through their 
cellular systems. Mobile stations that are subscribers in good standing 
to a cellular system, while receiving service from a different cellular 
system, are considered to be operating under the authorization of such 
different system. The licensee of such different system is responsible, 
during such temporary period, for exercising effective operational 
control over such mobile stations as if they were subscribers to it.
