I have found my lost device, how can I turn off Lost Mode and continue using my Lignes d'Azur card
Open the Find My app on another device.
Tap Devices, select the device you marked as lost, then click the Info button on the map.
In the Lost device section, click Lost Mode.
Click Turn Off Lost Mode, then click Turn Off to confirm.
You can also turn off Lost Mode on the lost device by entering its passcode (the one you use to unlock your device). If you turned on Stolen Device Protection on your iPhone, you may need to use Face ID or Touch ID.
