I am travelling to Russia, and tried to use the services of this company - windowsphoneunlock.com - to unlock my phone. They claim on the web site that it takes "up to 72 hours" to unlock the phone.
After waiting for 3 days, no response, I sent them an email, asking about the status. They responded that "some Windows Phone 7 devices take longer", and they will be clarifying this on their web page. However, they are confident that they will have the code in 24 hours.
Two more days go through, no code in the mail. I send them another query. This time, the response:
Please accept our apologies with the length of time it is taking to acquire your unlock code. This is because it is with AT&T. It seems that they will not be giving out the unlock codes for several months after the phone has been registered, or until June 2011. We have just had your order returned to us as not found, not surprising as we are finding out no-one can get codes for Windows Phone 7 handsets on AT&T. However along with yours and other returns of not found came back one successful code return, which is peculiar. I don't know if this is a one-off or it means with some other techniques it might be possible.
I appreciate it has been a long time to wait, so at this point can you please advise if you want a full refund, or you want us to keep trying other techniques.
Many thanks for your patience,
(1) They claimed that they could unlock Windows 7 phones, but they did not actually check it.
(2) The way they unlock phones is by simply asking for the code from AT&T on your behalf. Or, you can do it yourself and save the money. Of course, in either case AT&T does not supply the unlock code unless you own the phone for 90 days, as any customer service rep will tell you, which is why they couldn't "unlock" mine.
So stay away from these "services" and save yourself some time and money.
