How do I update my IQOS 3 DUO?
With the IQOS web app, you can update your IQOS 3 DUO to the latest version of the firmware in a few steps.
To update your IQOS 3 DUO device, start by connecting your device to the IQOS web app. To do this, login to your account and go to "My devices / Manage my IQOS".
iOS users: standard browsers don't allow you to connect via Bluetooth®, so you'll need to download the free Bluefy browser from the App Store. Bluefy is an Internet browser, just like Google Chrome or Safari. It connects your iPhone with our website via Bluetooth® to securely pair and manage your IQOS 3 DUO device. Bluefy is secure and convenient and won't take a lot of space on your phone. Make sure to keep Bluefy on your iPhone to access the IQOS web app whenever you want.
