How to set up QuantVPN on an iPhone and what to do if the app is not in the Russian App Store

Updated November 12, 2026

On iPhone and iPad, QuantVPN works through the Happ or INCY app. Both work with the same link from the bot.

If the app is already installed

  1. Open the link from the bot on your iPhone.
  2. Tap "Add subscription" and confirm in the app.
  3. Choose a country and turn the VPN on. On first launch, the iPhone asks for permission to add VPN configurations: tap "Allow".

Do not delete the installed app. Happ and INCY are currently unavailable in the Russian App Store, and you will not be able to install them again with a Russian account.

If the app is not in the App Store

The app is available in the stores of other countries. There are two ways to install it.

Option 1. Change the country in the App Store

Before you change the country, Apple asks you to spend any remaining balance on your account and cancel active subscriptions.

  1. Open "Settings" and tap your name.
  2. Choose "Media & Purchases". If the iPhone asks, sign in to your account.
  3. Tap "Country/Region" and choose the new country.
  4. Accept the terms, then enter a payment method and an address.
  5. Find Happ or INCY in the App Store and install it.

Apple has a detailed description on its site: Change your Apple Account country or region.

Option 2. A separate account just for the App Store

This option does not affect iCloud, photos or contacts.

  1. Create a second Apple Account with a different country.
  2. Open "Settings", tap your name, then "Media & Purchases" and "Sign Out".
  3. Sign in there with the second account.
  4. Install Happ or INCY from the App Store.
  5. Switch back to your main account the same way.

App updates come from the store where the app was installed.

Watch out for similar names

The Russian App Store has apps with names like "Happ Plus VPN ++". They have nothing to do with the real Happ and do not work with our subscription.

Common situations

Connected, but sites do not open. Open the Happ settings, update the subscription and reset the app settings. Then add the subscription again.

The VPN stopped turning on after an iOS update. In the Happ settings, choose "Recreate tunnel configuration".

A Tunnel.appEx error appeared. Tap "Yes", and the app will recreate the configuration. If that does not help, restart the iPhone.
