Mobile Access in 3 Steps
Getting the 399vat app running on your phone does not require a complicated setup. Whether you're using an Android or iOS device, the path from your handset to your account is short. We do not require you to sideload files or search third-party stores — start from our site directly. Access and availability depend on your local law and eligible regions, so
confirm this applies to you before proceeding.
- Open the current 399vat site — Go to 399vat in your phone's browser. The mobile layout loads immediately — no separate address or redirect needed.
- Check app or browser option — Look for the app download prompt on the homepage or navigate to the app section. The site shows you which access method — native build or browser shortcut — is currently available for your device.
- Sign in with your account — Use your existing 399vat credentials. If fingerprint login is enabled on your phone, activate it from account settings on the first sign-in so future visits skip the password step.
- Add to home screen if prompted — On some devices, the site will prompt you to add a home-screen shortcut. This places the 399vat icon on your launcher so access from your phone feels the same as opening a native app.
