best PCRF for pre-paid mobile solutions?

[scubacuda at gmail.com (Rogelio)]

I am researching some PCRF solutions for some work I am doing with
non-US operators, and I am looking for features that work well in
pre-paid mobile environments, particularly ones that want to cap or
charge 3G and WiFi at different rates / levels.

Any suggestions or contacts?
