I have a Japanese handset, a Kyocera Digno S (model KYL21). It was purchased and used in Japan. I would like to have it unlocked for use in the US, but my previous carrier, KDDI au, refuses to do anything. And seeing as how the phone is uncommon I am unable to find an unlock code. I have read that I may be able to send the phone to a third-party company to be scanned and unlocked but I haven't been able to find any such companies via Google.
Does anyone here provide such a service, or alternatively, can anyone here recommend a company that will scan and unlock my phone?
