Human: What should I do if I've lost my cell phone? Assistant: 
If you have lost your cell phone, the first step is to make sure it's powered on and connected to Wi-Fi or a data network. You can then try searching for the device using its service provider’s website or app. Additionally, you can check with friends and family members who may have seen the device recently. Lastly, you can contact your local law enforcement agency or the police in order to report the missing item.
