What is an eSIM?

An eSIM (embedded SIM) is a digital SIM card built into your phone. Instead of slotting in a plastic card, you install a mobile plan by scanning a QR code — and you’re connected. A Volo eSIM gives you data abroad with no roaming bills and no airport SIM queue.

How does it work?

  1. You buy a Volo plan and receive a QR code by email within minutes.
  2. You scan it once (on Wi-Fi) to install the eSIM profile on your phone.
  3. When you land at your destination, the eSIM connects to a local network and your data is live.

eSIM vs a physical SIM

  • No plastic card — nothing to lose, swap, or wait for in the post.
  • Keep your home number — the eSIM runs as a second line beside your normal SIM, so calls and texts still come through.
  • Instant — delivered by email in minutes, set up before you fly.
  • No roaming bills — one flat price paid upfront.
  • Multiple plans — store several eSIMs and switch between countries.

Is my phone compatible?

Most phones released from 2018 onward support eSIM and just need to be carrier-unlocked. Check the full list on our Compatible devices page.
