The first step; which is completely clear, is that the Telegram application must be installed on your phone. If not, you can download it from Google Play through this link.
The second step; is to find the desired movie in Telegram channels or groups. You have two solutions for this.
The easiest way is to use the Telegram search, which you can see after opening the Telegram application on the top of your mobile phone screen.
Enter the name of the movie or series you want.
The second solution is to join channels and groups or bots that put movies and series in them for free download. To find these bots or channels, you can use Google search, which is much better than Telegram search.
The best solution is to use the first method and join those channels after finding the desired movie.
Third step; After finding the desired movie or video, download it. By clicking on the file or the downward arrow, the file will start to download. After completion, the play option will be activated for you. You can also find the desired file inside your phone and run it from there or transfer it to other devices.
