Orange network info

[Guest unoturbo]

Hi,I have a C500 mobile I going to app unlock, but I need a Orange sim card for that.

But can I program a simcard, so that the c500 thinks it's a Orange simcard in it? I have simcard reader/writer. And a simcard that is empty!

So I need some info on the network. And what is the phone looking for on the simcard?

Thanks.
