Frequently Asked Questions
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of swapping physical cards, you download a data plan via QR code. It works just like a regular SIM — but without the plastic.
What's the difference between eSIM and a physical SIM card?
A physical SIM is a removable card; an eSIM is a chip soldered into your phone. eSIM lets you switch plans instantly without visiting a store or waiting for delivery. Most modern phones support both.
Which phones support eSIM?
iPhone XS and later, Samsung Galaxy S20+, Google Pixel 3+, and most flagship phones released after 2020 support eSIM. Check our device compatibility page for a full list.
