Troubleshooting Polestar & Volvo eSIM

"Add cellular plan" option missing: Confirm the vehicle runs the Google built-in (Android Automotive OS) system. On Polestar 2, an OTA software update may be required — check Settings → System → System update. Earlier software versions may not expose the eSIM menu.

QR code camera won't activate on display: The in-car QR scanner requires the vehicle to have cellular coverage to initiate the download. If the camera won't open, try the manual SM-DP+ entry option instead.

eSIM active but no signal: In the center display, go to Settings → Connectivity → Cellular Data → select Roamix → enable Data Roaming. Toggle Airplane Mode on/off in connectivity settings to reset network registration.

Vehicle Hotspot not available after eSIM install: Go to Settings → Connectivity → Vehicle Hotspot and enable it. Hotspot functionality is separate from the eSIM profile and must be turned on manually.
