Setting up on a computer
Start the Telegram bot on your phone or in Telegram for desktop and ask for the trial link.
Download a client from its official project page, not from a file-sharing site. Beware of search results that promise a free full version of a paid product: those are the ones that carry unwanted software.
Open the client and add a subscription from the clipboard.
Select a location. Amsterdam, Frankfurt, London, Dubai and Singapore are available.
Connect, then check your address in the browser. If it changed, the tunnel is carrying your traffic.
Which machines and systems
Windows 10 and 11 are covered by the mainstream clients, and macOS has an app too. Linux users usually pick a client with a graphical interface, or a command-line one if they prefer it. A Chromebook is a different case: it can run Android apps in many models, which makes the Android route the simplest. Each of these has its own page here, so this one only points the way.
An older system such as Windows 7 is its own problem, because clients stop supporting old releases. Plan on a newer system if you can.
Browser add-ons are not the same thing
An add-on for a browser only moves that browser's traffic. Your mail program, the update service of the system and the games on the machine go around it. If you want everything on the laptop to travel through the tunnel, the client route is the right one, and an add-on is only worth considering for a quick, narrow job.
Choosing, and a note on who is writing
When you compare ways of getting a laptop connected, judge by what you can verify: where the client comes from, whether it is maintained, what it asks to install, and whether traffic stops if the tunnel drops. Since the service behind this page is ours and is sold, read the criteria as a checklist for any option, ours included, and not as an endorsement of ours alone. Who wrote it? An AI tool gave us the outline, and an editor finished the wording.
