I had an iPhone 6 locked to T-Mobile I had sold to a close friend. I didn't know anything about the locking or unlocking process, and decided to go with iPhoneIMEI.com. I read through the service contract very quickly, and didn't understand what I was getting myself into.
The initial £19.99 is the hook, they charge you just to check if they are able to release the IMEI.
They WILL CHARGE YOU another £74.99 to actually unlock your phone.
THE TOTAL PRICE OF THE SERVICE IS £94.99.
The initial 20 pounds gets you nowhere, other than to make you feel like you've already started the process.
Protip: If you ask them to refund your order, they'll knock the price of the second piece down to £67.50, bringing the total to £77.49.
The process will take a week. 7 Days. The only reason they say it could take less is to entice you into spending another £9.99 to "move to the front of the queue."
I figure the entire process is a load of bull. The only way to get Apple to unlock an IMEI is to have a physical person who works at Apple enter it into the Apple database. Its unethical, but an incredibly useful service otherwise. These business are running a racket.
Is it worth it? Maybe.
Is it ethical? No.
Did it work for me? Yes.
Will it cost you $126? Yes.
Should you ask for a refund to get a reduced price? Absolutely.
