There are plenty of free VPN service available on mobile device.  I am listing here those that you can configure on your Windows, MAC OS or Linux system

Windscribe

Pro

  • offer 2GB/month without confirming your email. 
  • 10GB/month free when you confirm your email address. I suggest you to use a fake/disposable email if you want to enjoy larger bandwidth.
  • Refer a friend to get additional 1GB/month. Use my refer a friend link if you are keen on getting extra GB but you need to confirm your email before you get the extra GB.  You must register via browser and not from the apps you download or you won't get the extra 1GB when using my refer a friend links.
  • Free Windscribe support p2p as well.
  • Free plan allow access to 11 locations
  • Provide step by step guide at their website on how to configure on Windows, MAC OS and many other Linux distribution.
  • As of October  2018, works with Youtube, Whatsapp in China

 

If you need to access to more than 11 countries, consider sign up Windscribe Pro plan using my affiliate links.  You must register using my affiliate via the browser before proceed with payment as the affiliate link won't pass on to the iOS Apps store or Google Play Store.  

 

Cons

  •  You are limitted to the free bandwidth allocated to you on monthly basis.  

 

 

VPNBook

Pro

  • Doesn’t have any bandwidth limitation but 
  • No registration require and therefore completely anonymous.
  • VPNBook support openvpn and so far has been free for many years.

 

Cons

  • Its password get change every few weeks.
  • No p2p support for US/CA server.

I won’t be listing other VPN that offer free for limited time as I presume if you are looking for free VPN won’t be planning to sign up for paid VPN.
