That worked very well for me.

Now that we have the 3 values we needed from the SIM card (2 flags +
SPDI list), we could now also implement the "RequiredNameDisplay"
property which contains the whole logic for us, as Dan suggested
earlier. Given that this value depends on the current 3GPP operator ID,
I would really include that new property in the 3GPP interface. Will try
to implement this later on today.
