How do I use the SIM card when updating the one App?
- SIM card required: To reactivate the one App after an update, a SIM card may be needed to receive the SMS code.
- Temporary use: You can temporarily use the SIM card from another device.
- Wi-Fi option: After reactivation, the app also works without a SIM card via Wi-Fi.
Note: Devices without a SIM card slot can only be used for initial registration via Wi-Fi. Reinstallation is not possible without a SIM card.
