Model lists go stale the moment a new phone ships. Rather than trusting a checklist you found once and never re-checked, do this first: dial *#06# on your phone. If an EID number shows up alongside your IMEI, your handset has an eSIM chip in it, full stop. No EID, no eSIM, regardless of what the box said.
That test settles the hardware question. What it doesn't settle is whether your specific unit has eSIM switched on, which depends on where it was sold - more on that below.
iPhone
Every iPhone from the XR and XS onward has eSIM hardware, which by 2026 covers essentially anyone due an upgrade this decade. That's XR, XS, XS Max, and every numbered and Pro model since. Go to Settings > Mobile Data and look for "Add eSIM" - if it's there, you're set. Older models - the X, 8, 8 Plus, and anything before them - don't have the chip at all, no matter what settings you dig through.
Samsung Galaxy and Google Pixel
Samsung's Galaxy S20 and everything after it - S20 through the current S-series, plus most Z Fold and Z Flip models - supports eSIM. Google's Pixel line has supported it for even longer, from the Pixel 3 onward. Both brands list it under similar menus: Connections or Network & internet, then a SIM or "Add eSIM" option.
Budget and mid-range lines from either brand are less consistent - a Galaxy A-series or an older Pixel A model may or may not have the chip depending on the market it was built for, which is exactly the kind of thing a model name alone won't tell you.
