I am new to GPRS and I am finding it hard to find enough information to get started properly. I have scanned quickly documentation for different GPRS modems and that doesn't seem bad. What I would like to know is the following:
If you connect to the internet using a high speed connection from our office and you like to have an App that can communicate messages to GPRS enabled devices in the field what do you do. My understanding is that the GPRS mobile device establishs a connection with the provider which in turn assigns an IP address to the device. How does the server app finds the mobile device IP address, and how do you communicate to 100 devices ( for example from one App ).

Any example source code in VB is really appreciated.
