I am going to China next week. I know that I cannot use the phone there. However, I would like to use some of the functions of my phone. I want to use the camera, the alarm clock, games, etc. I am afraid that I turn the thing on I will be accessing things that I will be charged for. I currently have an unlimited data plan. Can I access data in China without an additional charge? Can I use anything over there? Any help would be appreciated.
