"Unable to complete cellular plan change" (iPhone): Usually means your device is carrier-locked. Settings → General → About → Carrier Lock must say No SIM restrictions. If locked, contact your original carrier to request an unlock.
"Couldn't add mobile plan" or "Activation failed" (Android / Samsung): Confirm device is unlocked, ensure you're on Wi-Fi, and try the manual activation code instead of the QR code. Restart and try again.
"SIM not supported" or "Device not compatible": Your device either has no eSIM chip or is carrier-locked in a way that prevents eSIM use. Check for an EID number. China-region iPhones and South Korea Samsung devices do not support eSIM — a different device is needed.
"No activation code found" or activation field missing (iPhone): iOS version is too old. eSIM requires iOS 12.1 or later. Settings → General → Software Update.
Activation code accepted but nothing happens
Restart your device and check SIM settings — the profile may have been added silently. If nothing has appeared after a restart, try the other installation method (QR or manual).
