You should pay to get a better service. It’s difficult for free VPN providers to match the service quality and internet safety a paid provider offers, so you’re more likely to experience slow connections, weak security, and having your device used as a proxy for other customers. If you use a free VPN, its creators have to make money somehow, so they may shower you with ads, track and sell your data, or even use your device to route other people’s traffic through — a reliable paid VPN provider won’t.
