Quick setup in 5 minutes
Open the App Store and install V2RayTun (recommended) or Streisand
Go back to the bot and copy the VLESS link you received. It looks like this:
vless://xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx@...
Open V2RayTun app → tap "+" button (top right) → select "Import from clipboard"
Select the added server from the list and tap Connect. On first connection, iOS will ask permission to add VPN configuration — tap "Allow"
A VPN icon will appear in the status bar. Now you can freely browse the internet!
The process is similar on all platforms: install app → import VLESS link → connect
