<human>: What should I do if I've lost my cell phone?
<bot>: If you have lost your cell phone, the first thing you should do is check with your service provider to see if it has been reported as lost or stolen. You can also try calling the phone number listed on your phone and ask for a message to be left for you. Additionally, you may want to contact the police if you are unable to locate your phone. Finally, consider setting up a Lost Mode feature on your phone so that if someone finds it they can call you.
