MNC/MCC as string?

Hi Remi,

Well, the point is that leading zeroes are meaningful (much like with phone

I understand perfectly.  But remember, oFono does not expose the user to
such details.  Manual registration is accomplished by using Register()
method (with no arguments) of the NetworkOperator interface.  The internal
storage representation is never exposed.  Thus it doesn't matter whether
internally it is a string or short, etc.

The attributes are really only for informational purposes only.  The user
would not base his decision on the mcc/mnc, but on the operator name.

So before we start changing the D-Bus APIs, we need to answer these two
questions:
  - Can a country/administrative domain have both 001 and 01 MNCs such that
the use of string for the MNC is actually necessary.
  - What does the user find easier to use, a string or a short?

Regards,
