These guys are the professionals.
I recently bought a Samsung Galaxy A7 which is locked to the US AT & T network. I lived outside of the USA and they were very helpful to assist me identifying the network my phone was locked to, the imei number and so forth. Within a week I recieved my network unlock codes. Thanks guys.
