You can change your IP address with a free VPN. Still, it’s not advisable due to the possible IP leaks, potential security breaches, and privacy concerns they hold.  For example, a free VPN may help you bypass ISP internet data surveillance so that it gets front-row seats to harvesting your internet data instead and selling it to the highest bidder. Likewise, some free VPNs hold a false sense of security by leaking your actual IP address through their unsecured tunneling technology. Thus, you’re still at risk of getting discovered and deanonymized on the network.
