hello i found my iphone how can i cancel the stolen mode

Turn off Lost Mode on an iPhone, iPad, iPod touch or Apple Watch

1. In Find My iPhone on iCloud.com, click All Devices, then select the device that is in Lost Mode.
2. Click Lost Mode, click Stop Lost Mode, then click Stop Lost Mode again.
3. You can also turn off Lost Mode by entering your passcode on the device.

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 Travel cards), when you turn off Lost Mode and sign back in to iCloud, you can use them again.
