# eSIM FAQ

> Quick answers about Fizen eSIM — phone numbers, hotspot, top-up, validity, and more.

<AccordionGroup>
  <Accordion title="Does my eSIM come with a phone number?">
    No — Fizen eSIMs are **data-only**. You keep your regular number active on your physical SIM for calls and SMS, and use the eSIM for internet. WhatsApp, Telegram, and iMessage keep working with your existing number.
  </Accordion>

  <Accordion title="How do I pay?">
    Two ways: **USDT** straight from your Fizen wallet balance, or **Visa/Mastercard via Stripe**. No bank account required for the USDT route.
  </Accordion>

  <Accordion title="When does my plan's validity start?">
    Validity starts when the eSIM **first connects to a network** at your destination — not at purchase. Buy days ahead and install before you fly.
  </Accordion>

  <Accordion title="Can I share my connection via hotspot?">
    Yes — hotspot/tethering is supported. Keep in mind that sharing drains your data allowance faster.
  </Accordion>

  <Accordion title="What happens when my data runs out?">
    Buy a new plan in the Fizen App in a few taps — it activates on the same eSIM. Check your remaining balance anytime in **eSIM → My eSIMs**.
  </Accordion>

  <Accordion title="Can I use one plan in multiple countries?">
    Yes, with a **regional plan** — one package covers every country in the region (e.g. Europe, Asia). Single-country plans work only in that country.
  </Accordion>

  <Accordion title="I deleted my eSIM by accident — can I get it back?">
    A deleted eSIM can't be reinstalled from your side. Contact support via the **in-app live chat** — under the [1:1 Trip Guarantee](/help-center/fizen-esim/trip-guarantee), we'll issue a replacement for any unused data at no cost.
  </Accordion>

  <Accordion title="Will my regular SIM keep working?">
    Yes. Your physical SIM and the eSIM run side by side — just make sure **mobile data** is set to the eSIM so you don't pay roaming on your home line.
  </Accordion>

  <Accordion title="How much data do I need?">
    Rough guide: maps + messaging ≈ 0.5 GB/day, social media + photos ≈ 1 GB/day, video calls + streaming ≈ 2+ GB/day. When in doubt, take the bigger plan — Fizen's per-GB pricing is the cheapest on the market.
