Not supported outside China.
Conclusions: Not a bad phone, esp for the price, but it is not even listed as available, let alone supported, on lenovo's websites in Australia /America or Europe. And as the ZUI interface is pretty buggy, that is an issue (in Settings, wallpaper can't be changed -keeps crashing-, data use can't be seen -goes to a china only page-, the ?google? news page -swipe left from home- is in Chinese and can't be changed, there is no launcher to show installed apps,... ), and it has not received a security (or other) update
