How to install an eSIM on Samsung
Samsung Galaxy phones install an eSIM from Settings → Connections → SIM Manager → Add eSIM. After scanning the QR code, set Mobile Data to the eSIM and switch Data Roaming on under Settings → Mobile Networks. The installation itself costs nothing — the package starts at your destination, not at your desk.
Which Samsung phones support eSIM?
Recent Galaxy flagships and many mid-range models do, but support depends on the model and on the market it was sold in. Check for an EID: dial *#06# and if an EID appears, eSIM installation is possible on that phone.
Where do I add the eSIM on a Samsung phone?
Settings → Connections → SIM Manager → Add eSIM. The camera opens so you can scan the QR code from the activation email.
The eSIM is installed but there is no internet. Why?
Usually one of two switches is missing: Mobile Data must point to the eSIM, and Data Roaming must be on (Settings → Mobile Networks). If the phone still does not attach to a network, restart it once.
