When using the US Unlocked Card as a form of payment on U.S. websites we always recommend to be connected over VPN.
VPN means Virtual Private Network. It is a method used to add security and privacy to private and public networks. A VPN connection works as a tunnel and converts your IP address into the I.P. address provided by the VPN provider.
A VPN connection protects your computer and communications on the internet against hackers and security breaches.
Use any of the recommended VPN providers below and download and install the software. Enable the connection each time before you use your card. To check whether your VPN is working you can go to whatismyipaddress.com.
