I take it they have the correct Message Type Indicator (part of
the PDU-type octet).

Unless you specify the message storage, the medium to be used is
left to the manufacturer's discretion (GSM 07.05). If you've
asked for a message to be stored on the SIM specifically and
that's full, I think the manufacturer is required by that
standard to use any other available storage.

Doesn't the user get asked whether they want sent messages
saved? Maybe saving them is the default setting on some
phones. As I mentioned earlier, the storage place (SIM or
phone) will default at the manufacturer's whim.
