Experiments in circumventing state censorship

All tests done in October 2017 in mainland China (several provinces).

Notes

  • The Trying to download a VPN.log file shows that some files are fingerprinted and are blocked even over an encrypted SSH connection. No idea how that is possible. Please leave a comment or send me an email if you have a clue.

VPN apps can be installed on iOS

  • ExpressVPN works on an iPhone SE with iOS 11. Does NOT work on an iPhone 5S with iOS 10. Support could not help.
  • VyprVPN works on both iOS 11 and iOS 10.

You have to install and set these up before reaching mainland China, as installing them there is now blocked from the App Store. You can however buy the full version while there, but over an uncensored connection. That means you have to download, install, register your account and start a free trial before arriving, and have to buy a full version before your trial expires.
