Have you found better rates to Poland mobile? Probably yes. How do they do this?

Of course, it's illegal here, not by the national telecom law, but by the operators' ownership rights - Polish SIMs are formally properties of the operators and FCT usage is a violating of T&C's of someone's property .
The same trick applies to many other countries .

Voicetrading charges:
Poland (Mobile) 0.0489
with ability to set CLI, so they are probably not using a Sim box.

I understand the working of a Sim-box (the idea behind it), but I still don't understand how Betamax has so many rates that are below 'the possible'.
I can 't believe that they deliberatly loose money to make money on other destinations. Have they found holes in the system? Possible, but how can they keep doing it for such a long time without getting caught?

Maybe Andy knows more ?
