I am still in dispute with them after 2 weeks without a phone as the unlock codes did not work.
I have sent them no less than 17 emails as I have not had even so much as a confirmation that they are dealing with the issue of the wrong unlock codes being sent out.
The only thing I will say that I am pleased about with them, is that I could pay with Paypal so that I am covered by them with their buyer protection policy.
If you are considering using mobileunlocks.com, then I suggest you use Paypal to pay also. At least you have a chance at getting your money back by doing so.
In my experience? They are just another one of the many fraudulent unlock companies out there that just take your money and when they've done this to enough people, they'll shut down and keep the cash.
SCUM.
