can you read Chinese ? If yes that would be easier for you to reset this phone. Maybe China mobile operation is a little different. You can go to the after-sale service to ask for help...it would save you a lot trouble

I am a Chinese guy, we usually surf China internet during our leisure time or play online game.

Hainan is the warmest city in China, there is no season winter, summer all around the year. It's quite a place for China coastal tourism maybe someday you could take a visit in Hainan city, you will remember it forever.
