# How to Buy an eSIM

> Buy a Fizen eSIM with USDT or card, and activate it in one click.

<Note>
  **Buy before you fly.** Install your eSIM before departure so you're connected the moment you land.
</Note>

## Purchase

<Steps>
  <Step title="Open Fizen App">
    Go to the home screen and tap **eSIM**.
  </Step>

  <Step title="Search your destination">
    Type the country name. You'll see available data plans with pricing. Regional plans cover multiple countries in one package.
  </Step>

  <Step title="Choose a plan">
    Pick based on data amount, validity period, and coverage area.
  </Step>

  <Step title="Pay with USDT or card">

  </Step>
</Steps>

## Activate in one click

<Tip>
  **No QR codes. No manual setup.** After purchase, you receive an activation link — tap it once and your eSIM installs itself.
</Tip>

<Steps>
  <Step title="Tap the activation link">
    Right after purchase, you'll get the link via in-app notification and email. Open it on the phone you want the eSIM on.
  </Step>

  <Step title="Confirm the install prompt">
    Your phone asks to add the eSIM — tap **Allow / Add**. That's it, the eSIM is installed.
  </Step>

  <Step title="Turn on data roaming">
    When you land, enable **Data Roaming** for your eSIM line in **Settings → Cellular/Mobile**.
  </Step>
</Steps>

<Info>
  Most eSIMs activate within 1–2 minutes. Some destinations may take up to 10 minutes.

## Manual installation (optional)

Prefer to install manually, or setting up the eSIM for someone else's phone? You can also scan the **QR code** included in your confirmation email: go to **Settings → Cellular/Mobile → Add eSIM → Use QR Code** and follow the prompts.
