Get a trusted client and profile
Install the official client from its normal distribution channel. Obtain a profile from the operator of a reachable gateway you are authorized to use.
Import and approve intentionally
Import the configuration through the client’s supported flow and review the platform VPN permission when you choose to add the tunnel. Keep the private configuration out of support messages.
Check the actual connection
Confirm a recent handshake, expected internet egress and intended DNS behavior. A native BiTTU iOS release still requires its own Apple build, signing, packet tunnel extension and device validation.
