if it’s a world band phone, shouldn’t it be unlocked already?

world band means you can use it anywhere.
If you want local rates in europe, just buy a prepaid SIM card and dial away.
If you want your subscriber rates in the us, just use your US sim card.
I’ve used a tmobile sim card in a phone that was only available in japan, it worked fine.
