# Manual Installation

> Install your Fizen eSIM by QR code or by entering the activation code manually — step-by-step for iOS and every Android brand.

<Note>
  Most users don't need this page — the [one-click activation link](/help-center/fizen-esim/how-to-buy-an-esim#activate-in-one-click) installs everything automatically. Use manual installation when you're setting up on a second device, the link doesn't open, or you prefer QR/code entry.

  Your **QR code**, **SM-DP+ Address**, and **Activation Code** are all on the **eSIM detail screen** in the Fizen App, and in your confirmation email.
