Yes! While Surfshark does not offer a free plan, it does offer a 7-day free trial if you download the app from Apple App Store or Google Play Store. You can also receive free months of VPN service by referring others. You receive one free month when you refer a friend, and your reward increases as you refer more friends.
As a general tip, I’d be cautious about using a free VPN. While I can recommend some free (and safe) VPNs, you’ll find the trade-off is limited bandwidth, reduced server locations, pop-up ads, and slow speeds. It’s expensive to operate a VPN service, so no trustworthy provider will provide a quality experience at no cost. If it does, I can guarantee you’re paying in other ways. I’ve seen cases where shady VPNs secretly sell people’s browsing history, private data, and bandwidth to make money.
