Make sure your phone is CLEAN before place your order: http://www.t-mobile.com/verifyIMEI.aspx as you might end up having to pay for a "Cleaning Service" to use the phone in the USA (and we're not offering cleaning service)!
Warning: Do not use this service to Unlock IMEI from MetroPCS USA as you will receive a NOT WORKING CODE and you won't be able to claim for a refund! MetroPCS USA is not supported, only T-Mobile is supported so do not waste the time of our supplier sending Junk IMEI as you will end wasting your money.
We only refund for "NOT ELIGIBLE FOR UNLOCK" issue, we will not refund any complaint about "Communication Error" or "Server not responding. please try again later.". It is mandatory to check before ordering if your phone have "Server not responding. please try again later." issue. If the answer is yes then you can try to fix this error by performing a hard reset on your phone, or upgrading his firmware. Again make sure your phone can communicate with "Device Unlock App" server BEFORE place your order.
