These three VPN services are all FREE and you do not have to install anything on your computer to run them.
After registration, you will have 4 VPN server addresses, one from Italy, and the other three from USA, choose one and create a new VPN connection, then you can access the Macrovp free VPN service with your username and password.
If the domain addresses (such as us6.macrovpn.com) is not workable, you can try the IP addresses (such as 126.96.36.199), and if one VPN server is not workable, you can try another one.
The Macrovp website supports English, Spanish, Chinese and many other languages.
After registration, you can create a new Virtual Private Network connection with the VPN server address vpn.itshidden.com, and then you can access the ItsHidden VPN service with your username and password, but you need to reconnect every 20 minutes as a free user.
If the network access is not workable, you can try to change vpn.itshidden.com to 188.8.131.52.
3. USA IP
For free user, you don’t need to register, just download the USAIP.pbk file, and then double-click on the file and select one of the USAIP PPTP connections. After that, you can access the USA IP free VPN services with the username demo and the password demo.
But you will need to reconnect the USA IP network after every 7 minutes.
All the above 3 free VPN services are tested and workable here in China, if you have any problem to use them, please let me know by adding a comment below.
[Update] It seems that ItsHidden does not offer free VPN any more.
