Are you using the default transport order in your WebWorks application or have you set TCP_CELLULAR to be first?
If you are going through BIS/BES you will be using the BlackBerry APN connection. If you move TCP_CELLULAR to the top you will likely be using the carrier's APN to access data.

I try with TCP_Cellular and the app doesn´t work :-(
Can you explain with more details all the options? ( Any url that explain it?)
It´s very important, our clients take us a lot of complaints about extra-cost

Well.. that is a big old can of worms that you're opening up
I can't say that I'm an expert on Transports and their routing properties. They are a very complex and confusing part of the communications on a BlackBerry.
The best way that I can explain it, is that there are physical connections, and then there are VPN tunnels.
MDS = VPN tunnel to your BES server at your corporation
BIS = VPN tunnel to the RIM Network Operations Center and then out to the internet
TCP_Cellular = VPN tunnel to carrier entry point for internet
TCP_WiFi = VPN tunnel directly to your WiFi access point router
VPN Tunnel does not equal physical connection!
This means you can be using the MDS transport and it can be going over WiFi or cellular. Which it picks is done under the hood.
Which APN any of the Cellular transports connects on can be different for each and every carrier. From what I understand (and I may be wrong) the typical rule of thumb is that BIS/BES comes through the BlackBerry APN and TCP_CELLULAR goes through the carrier APN.
Also, depending on your carrier, some also charge for WiFi access. There unfortunately isn't a single rule that will cover all carriers.
