   A free VPN may offer basic features, but a paid service might be necessary for more advanced features.

4. Security and Location:

   • Use reputable services like NordVPN or OpenVPN for their established trustworthiness.
   • Ensure you're using a strong password and block public Wi-Fi if possible.
