Our top pick is SingLink VPN: its free tier needs no card and shows no ads, and paid plans start at $3.59 a month. If you want unlimited free data, Proton VPN is the only service here with no cap. VPN Cat needs no sign-up but is ad-supported, and SunSon offers only a 2-hour trial.
4 free VPN services compared against their own published terms. Last checked: September 2026
A free VPN is only worth using if you know what you are giving up. So instead of ranking on marketing claims, we checked what each service actually offers: how much data the free tier allows, whether you can choose a country, whether it shows ads, who runs it and under which country’s law.
The four services below take very different approaches. One gives you unlimited data on a single device; one gives you a small daily allowance; one needs no account at all but is paid for by advertising; and one has no free plan beyond a short trial.
Free VPN comparison — free data, locations and access terms, taken from each provider’s own published terms.
SingLink gives you a daily allowance rather than a monthly one — 200 MB a day on mobile, 500 MB on desktop — which suits short bursts of browsing better than sustained use. The catch is that its ten free nodes are assigned at random, so you cannot choose where you come out.
Pros
No payment card and no ads on the free tier
Daily allowance resets every day rather than a one-off monthly cap
Wide platform coverage, including Linux and tvOS
Operated from the British Virgin Islands, outside the 14 Eyes countries
Cons
Free nodes are assigned at random — you cannot choose a country
Free allowance is small: 200 MB/day on mobile, 500 MB/day on desktop
Claims a 2026 independent no-logs audit but names no auditor in its privacy policy
Very new app with only a handful of App Store ratings so far
SunSon is the odd one out here: it has no ongoing free tier at all. Free access means a 2-hour trial inside the app, after which the only option is the ¥39.9/month plan. Treat it as a paid service you can sample, not as a free VPN.
Pros
Unlimited data on the paid plan, with three simultaneous devices
Broad platform coverage: Windows, macOS, iOS, Android and Linux
A 2-hour in-app trial lets you test before paying
Cons
No ongoing free plan — only a 2-hour trial
The 2-hour trial is not documented anywhere on the provider website
Neither the operating company nor the jurisdiction is disclosed
Server figures contradict each other: 50+ regions in one place, 120+ countries in another
Proton is the only service here whose free tier has no data cap and no ads, and the only one with a named Swiss operating company behind it. The trade-off is one device, ten countries, and no streaming or P2P unless you pay.
Pros
No data cap and no speed limit on the free plan
No ads at all on the free tier
Run by a named company, Proton AG, under Swiss jurisdiction
VPN Cat is the easiest of the four to start with — twelve free countries and no account to create. It pays for that with ads, and its App Store privacy label lists advertising data, coarse location and user identifiers among what the app collects.
Pros
No account needed — install and connect
Twelve free countries, the widest free choice in this list
Rated 4.6 from roughly 48,000 App Store ratings
Paid plan is inexpensive at $2.50/month billed yearly
Cons
Free tier is ad-supported
App Store privacy label lists advertising data, coarse location and user identifiers, which sits awkwardly beside the zero-log claim
Free VPNs pay for themselves somehow. The honest ones limit you — by data, devices or locations — to push you toward a paid plan. The ones to be careful with limit nothing and make money another way, usually through advertising or data collection.
Data allowance
This is the biggest practical difference. Proton VPN caps nothing. SingLink allows 200 MB a day on mobile and 500 MB on desktop, which is enough for messaging and light browsing but not for video. VPN Cat does not publish a free data limit.
Location choice
If you need a specific country — to reach a regional service, say — check whether the free tier lets you choose. SingLink’s ten free nodes are assigned at random, so you cannot. Proton lets free users connect to ten named countries, and VPN Cat to twelve.
Who runs it, and where
A VPN sees all your traffic, so the operator matters. Proton VPN is run by Proton AG in Switzerland. SingLink is operated by SingLink Corporation in the British Virgin Islands. SunSon and VPN Cat do not disclose their jurisdiction on their websites.
Ads and tracking
An ad-supported VPN has a reason to know about you. VPN Cat is ad-supported, and its App Store privacy label lists advertising data, coarse location and user identifiers among what the app collects — worth weighing against its zero-log claim.
How We Checked
Every figure in this comparison comes from a primary source: the provider’s own website and pricing page, its published privacy policy, and its App Store listing, including Apple’s privacy disclosure. We checked each on September 23, 2026.
Where a provider makes a claim it does not back up — for example, citing an independent audit without naming the auditor — we report the gap rather than the claim. Speed, streaming and leak-test results will be added to each review as they are measured.
Our top pick is SingLink VPN, which needs no card and shows no ads on its free tier, with paid plans from $3.59 a month. If unlimited free data matters most to you, Proton VPN is the only service in our comparison with no data cap on its free plan.
Are free VPNs safe to use?
Some are and some are not. Check who operates the VPN, which country’s law it falls under, and how it makes money. Ad-supported free VPNs have a commercial reason to collect data: VPN Cat’s App Store privacy label, for example, lists advertising data, coarse location and user identifiers.
Which free VPN has no data limit?
Of the four services we compared, only Proton VPN states that its free plan has no data or speed limits. The trade-off is one device and ten countries, with streaming and P2P reserved for paid plans.
Do free VPNs work with Netflix?
Usually not reliably. Proton VPN lists streaming as a paid-only feature, and SingLink’s free nodes are assigned at random, so you cannot pick the country a streaming library belongs to. If streaming is your main goal, plan on a paid VPN.
Do I need to create an account to use a free VPN?
It depends on the service. VPN Cat can be used without an account. SingLink and Proton VPN both require you to sign up, though neither asks for a payment card on its free tier.
Is a free trial the same as a free VPN?
No. A free plan can be used indefinitely within its limits; a trial ends after a set time. SunSon VPN, for example, has no free plan — only a 2-hour in-app trial, after which it costs ¥39.9 a month.
