I'm going to be living in China for a few months.
My iPhone 4 is a Prepay/Pay As You Go.
If I get a Chinese Sim Card, will that have any effect on the iPhone other than changing the number?
Will it restart my device as a Chinese iPhone or will it still be the same?
Also, China has restrictions on some internet activity and communication - will the SIM allow my FaceTime or Skype to be affected?
