# 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 shortly before departure on trusted Wi-Fi, so you're connected the moment you land. If your regional/global plan also covers the country you're in now, install it but keep the line **off** until you arrive — connecting early can start the plan's validity.
</Note>

## Purchase

<Tip>
  **Check your phone first.** Use the device check in the app's eSIM section, or dial `*#06#` to see if you have an EID. It matters: an eSIM you haven't installed can still be returned, but once installed it can't. See [Supported Devices](/help-center/fizen-esim/supported-devices).
</Tip>

<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, card, or Apple Pay / Google Pay">
    Pay with **USDT** straight from your wallet balance, or pick a fiat method at checkout: **Card (Visa/Mastercard)** or **Apple Pay / Google Pay** for fast checkout with the cards already saved on your phone. Confirm, and you're done.

    Paying by card for the first time? Enter the details once and toggle **Save card for future purchases** — after that it's one tap:

    <Info>
      Card details are encrypted and handled by our payment provider (Stripe). Fizen never stores your card number.

## 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**.
