Free vpns are not a good idea. They're selling your data to make up for the fact that you're not paying for the service. Which defeats the whole point of having a vpn for privacy and security. You're better off with cheaper vpn options like private internet access vpn for $40 a year or $7 a month, torguard vpn for $60 a year or $10 a month and windscribe vpn for about $49 a year or $9 a month. These are the most affordable and trustworthy vpns with good quality and as you can see they offer huge discounts.
Pls stay away from free vpn services, your data safety and privacy is not their top priority. Remember all those servers they use require lots of money to maintain and the ad revenue just isn't big enough to generate enough profit for them. Some free vpns even try to save money on server costs by using virtual servers ie one server pretending to be multiple servers and this can greatly affect your speeds.
Long story short stay away from free vpns and buy a vpn subscription instead.
