This question was marked as a duplicate of What is the best free VPN service?
- Also, I know the new version of Opera has a free VPN built right into the browser. Although I have heard that there are privacy and security concerns now that Opera is own by a Chinese company - don't know if that's a truly the case, but just what I heard.
- +1 for Tunnelbear. You can use it on 5 devices concurrently. On a side-note - If a VPN is free, you are almost the 'fee' for it. Your data will almost be used to sell. When it comes to VPN, I'm of the opinion that it is best to pay for a good service that has good privacy policies.
