Will a VPN on a Iphone allow you to go on facebook on China?

The VPN i use is this www.freecanadavpn.com. It sets up and works and has the VPN sign on the top. But if i travelled to china would it allow me to go on Facebook, youtube… On the iphone connecting to a local Wi-Fi network? When i connect it doesn't tell me to like select a different location or IP address. So i'm not sure if this just works as a hotspot shield or if it actually allows you to go on facebook in china.

I suggest you go for paid vpn service because free vpn service not give so much encryption or security mostly isps tracked free services go for purevpn and express vpn service its paid subscription but both are cheap price try it these two services are best for china mostly time i traveld to china and i have my purevpn 1 year account and i'm almost connect with fb and twitter in china read detail information about purevpn service is here http://www.bestvpnservice.com/purevpn-review/
