Why V2RayTun is useful
V2RayTun is relevant when a device needs a client for Xray and VLESS/Reality profiles. It works well for users who want an explicit profile list and quick route switching.
For most users, the technical terms are less important than the order: open SochiVPN, get the profile, import it into V2RayTun and check the result in the account.
Basic connection order
Open connection options in SochiVPN, choose the device and use the V2RayTun profile. If QR, link or clipboard import is available, use that instead of manual entry.
After import, enable the profile in V2RayTun. Then return to SochiVPN and verify that the device state is clear.
What to do when it fails
If pages do not open, start with two checks: the active V2RayTun profile and the freshness of the SochiVPN profile. Do not edit low-level client settings before refreshing from the account.
If the issue repeats, contact support and mention V2RayTun. That narrows the connection scenario immediately.
