I used the code for SOL24 (Japanese KDDI model of Xperia Z Ultra) after I burned some ftf files of a global model, and a ROM which has been customized by an expert. The unlock code worked well and now I can use the docomo sim in SOL24. The only problem of this unlock code is its cost. It cost 28.99EUR, which is much higher than other models. For example, when I unlock LGL22 (Japanese KDDI model of LG G2), it cost only 6.99EUR in this site, and it is being sold for only 0.99GBP on eBay. Compared with these, the unlock code for Z Ultra is too expensive, so I reduce 1 star from my evaluation value.
