Terms & Conditions say that the initial payment "might" offset the overall cost of unlocking phone. Not true at all. Got charged an additional $50 on top of the $20 "pre-order" (the "pre-order" just says order when you purchase). Pretty scummy to not tell people upfront that they know it isn't going to just cost $20. Don't plan to just pay $20, it'll be more in the range of $75-200, just depends on arbitrary numbers they pull out of nowhere. No price break down or explanation for why my iPhone 7 costs that much extra to unlock from KDDI. Haven't tried other services, but I'm now assuming this one wasn't the cheapest. As you can see in the photo, while before you order, they say there "may" be an additional charge; their default order fulfillment email lets you know that there will always be one.
