How does the trial work? Is the 30 day refund the same as a trial?

Never used an VPN before. Want to try one with trial, but I am confused how it works. Can I pay for 30 days, then just say “I wanted it as a trial run”?

You can pay for 30 days, 6 months or 12 months. For all plans, the first 30 days are considered the “trial” or money back period. No matter which plan you select, you can ask for your money back during that time.

ExpressVPN is pretty expensive for the service they offer. I recommend Astrill or free vpns over it.
