Hey I'm planning on getting a SIM card here in Europe. Is it illegal to unlock an iPhone and what's easiest way? Sorry if this is in wrong thread.
Since the new unlock bill, the action will not be illegal anymore.
Yep, and the President signed it into law on Aug 1, 2014.

From what I understand (going out on a limb here), it's Apple who provide the unlocking mechanism, not the carrier. You pay the carrier, they notify Apple & they provide the code/s (through iTunes). It's never been illegal to unlock phones in Europe, at least not that I can remember.
I guess that if you don't have a contract with a European carrier you might have problems...
