An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of a small plastic card you slot in and out, an eSIM is a tiny chip soldered to your device's motherboard — and it works entirely through software.
How an eSIM works
Your carrier profile is downloaded directly to the chip in your phone. You can store multiple profiles at once and switch between them without touching any hardware. Activating an eSIM is usually as simple as scanning a QR code from your carrier.
eSIM for travel
Instead of paying roaming fees or hunting down a local SIM at the airport, buy a travel eSIM online before you leave. It activates the moment you land. Keep your home number active while using a local data plan abroad — no SIM swapping required.
Does my phone support eSIM?
Most flagship phones released since 2018 support eSIM, including iPhone XS and later, Samsung Galaxy S20 and later, and all Google Pixel phones from Pixel 2 onwards. Use eSIM Check to confirm your exact model.
