Travelling to China: How to get access to internet/social media?

Ill be travelling to China in a couple of weeks and would ideally like to be able to access Facebook etc to keep in contact with family and friends. Ill be using my iPhone 6s plus, and am using my current provider (vodafone australia). I've heard lots about downloading a VPN, but IIm not very tech savvy at all and need a simple way haha. Ta in advance!

First step: downlod mlg antivirus then put it to your pussi and lick it

It's doesn't require any kind of tech-knowledge to use a vpn.
For iPhone-
https://itunes.apple.com/...41430?mt=8
Install this and change your location(i'm not sure whether this feature is included in this).
Now you can access websites banned in china simple:-)

Welcome to communist china where they block and filter everything to the outside world. You will get a "filtered version" at best.
