We attempted to deliver your unlock Over The Air via 3G and Wifi, but were unable to do so.
We respectfully have to inform you that your iPhone is unfortunately marked by the carrier as either blocked/barred or in-contract. A handset can be blocked for non payment of bills, bad ESN or contract issues. As we have already prepared your unlock and incurred the unlocking charge, we cannot supply a refund for handsets which are rejected in such circumstances.
There are numerous services such as http://cleancheck.me (FREE) which can be used to identify blocked/barred handsets.
You have been refunded in Trade Credits in full which you can use on our website when purchasing another unlock simply by purchasing with this email address.
