What is an eSIM?

An eSIM is a digital SIM profile loaded onto a chip already inside your phone. No physical card. Activation is a one-time QR scan.

How an eSIM differs from a physical SIM

• No card to lose or break — the profile lives in firmware.
• Multiple profiles on one device — keep your home SIM active and add a travel eSIM next to it.
• Instant activation — scan the QR, no shipping, no SIM-swap.

Which devices support eSIM

• iPhone XS, XR, and every iPhone since.
• Google Pixel 3 and newer.
• Samsung Galaxy S20 and newer (region-dependent).
• Most 2020+ Android flagships and many recent mid-range models.
