Do not use iphoneimei.net for unlocking your iphone. It will said you must pay additional services to unlocked the iphone(74 dollar) when I already paid 27 dollar. It doesnt make any sense when they are not telling upfront. And when I requesting the full refund they said NO. And btw I already unlocked my iphone with just 20 dollar from attunlocker.us.
For people you want unlock their iphone, you can go to attunlocker.us
