How to Set Up Proton VPN on Android

A VPN encrypts everything your Android phone sends over the internet, so anyone watching the network it's on — a shared home Wi-Fi, a router someone else controls — sees only scrambled traffic they can't read. Proton VPN takes a couple of minutes to set up; below, you'll connect through a saved profile, then switch on the Android settings that keep it protecting you automatically.

The steps below sign you in to the Proton VPN app, so you'll need a Proton account first. The free plan is enough to get connected; a paid plan unlocks full speed and every server, and Proton Unlimited bundles in Proton Mail, Pass, Drive and more.

Once you're connected, Proton VPN's NetShield is already working — there's nothing to set up. It's worth knowing what it does.

NetShield filters your connection at the DNS level, stopping known malware domains, adverts and trackers before they load. On a paid plan it's on by default — blocking malware, ads and trackers — and you can change the level or switch it off under Settings → NetShield in the app. On the kind of network this guide is about, it strips away the tracking layer that would otherwise ride along with your traffic.

Android can keep the VPN running permanently and block any traffic that tries to slip past it — an always-on connection with a built-in kill switch. It's off by default and lives in Android's own settings, not the Proton app. Go to Settings → Network & internet → VPN, tap the gear beside Proton VPN, and turn on Always-on VPN and Block connections without VPN. From then on your phone won't go online unless the encrypted tunnel is up, so it can never quietly fall back to the open network.

A VPN runs quietly in the background, but there are a few normal side effects worth recognising so they don't catch you out.

A handful of websites, streaming services and banking apps detect and block VPN traffic, so now and then you might hit a CAPTCHA, an ‘unusual activity’ warning, or a page that simply won't load. That's the site's choice, not a fault with Proton VPN. If it happens, try switching to a different server — or one in your own country — or briefly disconnect for that single app. Banking apps in particular often prefer your normal connection.

Switching between Wi-Fi and mobile data, weak signal, or your phone waking from sleep can briefly interrupt the tunnel. Proton VPN reconnects on its own, so most drops are over in a second or two. If you turned on Block connections without VPN, your internet will pause for that moment rather than fall back unprotected — that's it working as intended.

Because your traffic now takes an encrypted detour through a VPN server, you may notice a small drop in speed — usually unnoticeable for browsing and messaging, occasionally visible on large downloads or video. Choosing a nearby server (the Fastest option, or one in your own country) keeps the difference to a minimum, and switching servers often helps if a connection feels sluggish.

Once in a while a single piece of a page — an image, a video, an embedded widget — won't load while the rest of the site works fine. Usually that element is served from an ad or tracking domain that NetShield is blocking, so it's a side effect of the ad-blocking, not a broken VPN. If you genuinely need it, drop NetShield to ‘Block malware only’ (or turn it off) under Settings → NetShield and it will come through.

Links that bounce you through a tracking or ad redirect before reaching their destination — sponsored search results and Google Ads links are the usual culprits — can fail with a DNS or ‘server not found’ error, because NetShield blocks the redirect domain so the hop never completes. Copy or type the real destination address directly, or briefly switch NetShield off, and the page opens normally.

A VPN closes the network door, but it isn't the only way back in. The account your Android phone runs on — your Google account — is the master key to your photos, messages, backups and location. If someone has its password, or can reach the email it's tied to, they can walk straight back in and the VPN won't stop them. That account is what to lock down next.

The biggest part of that is the email behind the account. A free inbox that has already been breached — or is easy to guess — quietly undoes everything else, so it's worth moving your most important account onto a private, end-to-end encrypted address. Here is why Proton Mail makes a stronger foundation.
