...this combined looks like your SIM says MobileNetworkCode 08 while the
network attached to is 24. So ofono thinks your are roaming now. Is an
update needed to some database? Is this in ofono or in some other sw?

Let's ask ofono ml for an answer.

The modem tells us it is roaming.  Nothing can be done about that.

I'm not sure what the context of the question is, but RadioSettings API
is completely independent of the current registration status.

The context was that SIM shows home network as 08 with the current
network being 24. The device thinks it is roaming while the user, in
this case Niclas Karlsson, knows the device should be in its home
network. So org.ofono.NetworkRegistration is the correct one here and
any change in roaming status must come from the network? So this boils
down to simply being connected to the wrong network after all?

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.
