What a VPN APK is, and the one question to ask first
A VPN APK is the installer file of an Android app, handed to you outside the Play Store. Sideloading itself is a normal Android feature. The risk sits in the file: an APK from a stranger can contain anything, and a tunnel app sees all the traffic that passes through it.
So ask who published the file before you ask whether it works. A client whose developer keeps a releases page, or a store listing with a named publisher, can be checked. A file posted on a forum thread or a "latest version" download site cannot.
Installing a client from a file, step by step
Get the subscription link first. Ask the Telegram bot; within roughly a minute you receive a personal VLESS link, and nothing needs registering: no account, no mailbox, no password.
Pick a client that takes subscription links. v2rayNG, Hiddify and Happ all take them; check each one's listing for its current price.
Download the file from the developer's own releases page or store listing, not from a mirror.
Open the downloaded file. Android asks you to allow installs for the app you opened it from, such as the browser or a file manager. Allow it for that one app only.
Install, open the client, paste the link, choose a server and connect. Accept the system prompt about setting up a VPN connection.
Go back into settings and switch the install permission off again for the browser or file manager.
Checking the file before you tap install
Since Android 8.0 the old global "unknown sources" switch has been replaced by a permission given per app, so a download cannot install itself unless you approved the app that opened it. That helps, but it does not make a bad file good.
A few habits that cost nothing. Compare the file name and version with what the developer's releases page lists. Where the page publishes a checksum, run a checksum tool on the file you downloaded and see whether the two values agree. Look at the size too: if the developer's page lists one size and your file is far smaller, that is a warning sign. Keep Play Protect switched on, because it scans apps whatever route they came by.
A tunnel app asks for the VPN permission and nothing beyond what its job needs. If a "VPN" asks for your contacts, messages or the right to read everything on the phone, stop and delete it.
Files sold as a "proxy server" for a game are another thing
Some search results offer an APK called a game proxy server, often with a version number in the name. Those are not clients for this service, and we cannot say what they contain or who runs the servers behind them. A game account can hold real money and years of play, so installing an unknown file that sees the traffic is a poor trade.
A game also decides for itself whether it tolerates a tunnel. Read the rules of the game you play before you route it anywhere.
When the store is the easier route
- Your phone has the Play Store and the client you want is listed there under a named publisher.
- You want updates to arrive on their own instead of checking a releases page.
- The phone is shared with a child or a relative who may tap the wrong file.
- You are not sure how to read a checksum. A store listing does that checking for you.
A word on how this page was prepared
Our keys are what this site sells, so the checks above were picked to be ones you can do without trusting us: a publisher's name, a checksum, a permission list. Before this went up, editors read an AI-assisted draft and matched it to what the service does: a bot-issued link, a client of your choice, five server locations. Whether you may sideload apps onto a phone from work or school is a matter for whoever owns that phone, and the rules can differ from place to place.
Questions and answers
Programme
Does the key work if I install the client from a file?
Yes. The link is the same whichever way the client got onto the phone. A single link carries no cap on devices.
Which servers will I see after pasting the link?
Manchester, Madrid, Singapore, Abu Dhabi and Toronto. There are none in India, so no Indian address is offered.
How do I know a download page is the developer's own?
Follow the link from the client's store listing or from the repository it names, rather than from a search result. Typing a name into a search box and clicking the first ad is how fake pages get visits.
Should I leave the install permission switched on afterwards?
Switch it off. You can grant it again in a few taps the next time you need it.
Can a VPN file be updated in place?
A newer file of the same app, signed by the same developer, installs over the old one and keeps its settings. A file from a different publisher will be refused, which is the system doing its job.
What if the phone says the app is blocked by Play Protect?
Read the message instead of dismissing it. If the file came from the developer's own page, you can check the name and checksum again; if it came from anywhere else, delete it.
