Sorry if I don't expand on the following.

1. The phone is already unlocked (at least here). But I can only use SIM cards that are international and not in my country. Of course this is fairly expensive.

2. The unlock fee may incur the difference from what you pay for a phone that is subsidized with a 2 year contract to the price you pay for a no-contract phone. I rarely see the unlock fee exceed this difference. It's not a ridiculous amount. Some can't wrap their head around this area.
