Go to icloud.com/find, then sign in to your Apple Account (if necessary).
In the list of devices, select the lost device.
If you already selected a device, select All Devices or to return to the list.
Select Lost, select Stop Lost Mode, then select Stop Lost Mode again.
You can also turn off Lost Mode by entering your passcode on the device. If you turned on Stolen Device Protection on your iPhone, you may need to use Face ID or Touch ID.
Note: If you had any cards suspended when you put your device in Lost Mode (credit or debit cards for Apple Pay, or student ID cards or Express Transit cards), when you turn off Lost Mode and sign back in to your Apple Account, you can use them again.
