I purchased unlock codes for an LG Pheonix 2 in September, receiving 4 possible unlock codes. After entering all 4 invalid codes, resulting in a carrier lock taking over a brand new phone, had to return the phone, then requested a full refund for the invalid unlock codes. I have yet to a refund or any further contact from Codes2Unlock. I will not attempt to use their services again and would not advise others to trust the unlock codes paid for and sent upon request.
