An eSIM (embedded SIM) is a digital version of the SIM card built into your phone. Instead of swapping a tiny plastic card, you install a mobile data plan by scanning a QR code. For travelers, that means you can be online the moment you land — no airport kiosks, no roaming bills.

How an eSIM works

Your phone has a small reprogrammable chip. When you buy a plan, you receive a QR code that contains the carrier profile. You scan it in Settings › Cellular/Mobile Data › Add eSIM, and your phone connects to a local network at your destination.

Why use an eSIM for travel?

• Instant: install before you fly, activate when you land.
• Cheaper than roaming: local rates without the carrier markup.
• Keep your number: run the travel eSIM alongside your home SIM for data, while still receiving calls/texts on your primary line.

Is my phone compatible?

Most phones since 2018 support eSIM (iPhone XS and newer, recent Pixel and Samsung Galaxy, and many others). Check our device compatibility guide.
