This is a SCAM! Seller will tell you that the unlock is "100% GUARANTEED" and then we they cannot unlock your phone you will get TONS of EXCUSES so they don't have to refund you your money. When you prove them wrong on their excuse they will come up with another excuse. I filed a complaint with PayPal to refund my money. DO NOT BE SCAMMED. Reach out to me if you want to see a copy of the entire conversation with them and I will be more than happy to share it. Will post it in Facebook too
Also, what's 100% guaranteed is you will get very poor responses from this seller. When you call their phone number there is no option to talk to anyone. They'll send you one E-mail a day and then you won't get a reply again until after the following day. They'll even respond rudely saying you have to wait and you're not the only customer sending them an E-mail. Very, very bad service.
