How does the service provider differentiate between data and VoIP as data?
For our mobile devices in trucks, we use GSM/GPRS communication. Our customers are paying for a certain data amount -- depending on the service package to which they subscribe. We use a modem in our device, which can do both data and voice. But as I understand it, with VoIP, everything becomes data. So, is it cheaper for the user if they use VoIP? How will operators handle this from a business model perspective? Will they expand the data amount packages or will they need to differentiate between 'regular' data and VoIP data? And a technical question: how much VoIP data am I consuming if I have a one minute voice conversation?

Providers can tell the type of packet that is being transmitted and most cell providers have an exclusion against using the data service for voice.
Each packet contains about a 20 milliseconds sample of the voice conversation. In order to determine how many packets you use -- divide the total conversation by 20msec. Remember you have to do this both ways.
