An eSIM (embedded SIM) is a digital SIM card built right into your phone. Instead of slotting in a plastic chip, you download a mobile plan over the internet and activate it in seconds. For travelers, that is a game-changer: you can buy a local data plan before you even land.
How does an eSIM work?
Your phone has a small programmable chip that can store one or more mobile profiles. When you buy a Turnaa eSIM, we email you a QR code. You scan it in your phone’s settings and the plan installs itself — no store visit, no shipping, no fiddling with tiny cards.
Why use an eSIM when you travel?
- No roaming bills. Pay local data prices instead of your home carrier’s roaming rates.
- Instant. Your QR code arrives by email in seconds — set it up at the airport before you fly.
- Keep your number. The eSIM runs alongside your normal SIM, so you still get calls and texts on your usual number.
- Nothing to lose. It is fully digital — no physical SIM to misplace.
Does my phone support eSIM?
Most phones released since 2018 do — iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and many others. The quickest check: open Settings › Cellular (or Mobile Data) and look for an “Add eSIM” option. If it is there, you are ready.
How do I install an eSIM?
- Buy a plan for your destination — your QR code is emailed instantly.
- Open Settings › Cellular › Add eSIM.
- Scan the QR code (or tap “Install on this iPhone” on iOS 17.4+).
- Turn the line on, set it as your data line, and you are connected.
