Have them download the Services Test app by Amsys and run the full suite.  It will test connectivity to the Apple Push Notification Server, messaging server, and other things.


Second, have them turn off Wi-Fi and see if the issue persists.  If it is resolved on cellular, they both have a networking issue.

    It sounds as if their iPhones aren't registered with Apple's message 
    server. It could be a configuration setting in their phones or an 
    authentication issue between the phones and Apple.
