When Travelling in China do I need to use a VPN or Proxy?

In some countries e.g. China, there is what is called a "Great Firewall" which blocks access to certain Western sites e.g. Facebook and Google.

Many locals use a VPN or Proxy to get round this. However when travelling with our eSIM services it is NOT necessary to use a VPN in these countries. All Western websites will be available as normal.
