You can, but it’s not recommended. Most free VPNs only offer a very limited number of poor-performing servers, while enforcing tight data caps. Many free VPNs do not manage to hide your real IP address either, so you won’t have access to region-restricted apps and other purchases. Some may even purposefully share your data with third parties to make a profit. Using a premium (but affordable) VPN like ExpressVPN with a trusted money-back guarantee is a far better option.
