the number of operators that provision this properly on the SIM card
they hand out is really limited. I only know of a view and they only do
that for the voice customers. For the data sticks, they do not care.

In most cases this is not provisioned properly. The best you can hope
for is that the an operator updates these values via SIM Toolkit or some
sort of network initiated USSD. Otherwise you are really out of luck
here until you manually modify the SIM card.
