I pay blau (my operator?) who just is a reseller for the eplus network
(my service provider?).

   string "blau"
   uint32 0
   uint32 0
   int32 0

This is what is shown my the home widget.

   array [
   ]
   int32 1003

My suggestion was to eavesdrop on what the plug-in is doing.  You
could just eaves drop on the whole system bus and then grep of the
strings you are looking for.  I have a few weeks worth of such logs
and I found one relevant reference:

  method call sender=:1.33 -> dest=com.nokia.phone.net serial=293
  path=/com/nokia/phone/net; interface=Phone.Net;
  member=get_operator_name
     byte 0
     uint32 3
     uint32 262
  method return sender=:1.20 -> dest=:1.33 reply_serial=293
     string "E-Plus"
     int32 0


HTH,
