This all depends.  The operation in question might be an MVNO, or the
operator has an agreement to "roam" on a network but all traffic be
treated as "home" for billing purposes.  There are very nasty details of
how the operator name is presented in these circumstances.  In certain
'roaming' conditions, the operator is presented just like it is a home
network.  See EFspn and EFspdi handling if you're curious.

This is what might be happening here.  The user is not connected to a
"home" network; however for all intents and purposes he is not really
roaming.  The current roaming logic uses the registration status as
reported by the modem firmware, which may not be satisfactory in this
particular situation.
