What is an eSIM?
An eSIM is a SIM card that's built into your phone — there's no plastic card to buy or insert. When you choose a CALAFLY plan, we send you a QR code: scan it once and your phone downloads the SIM over the internet, ready to use at your destination.
Your phone keeps its regular SIM, so you can still receive calls and texts on your usual number while using CALAFLY for your data.
