<human>: What should I do if I've lost my cell phone?
<bot>: If you have lost your cell phone, the first thing to do is check with family or friends who may have seen it. You can also try calling your phone number from a different phone or by using an online tracking service such as Google Voice or Find My iPhone. Additionally, you can look for your phone in public places where you might have dropped it, like restaurants or coffee shops. Lastly, you can contact your carrier and ask them to help locate your phone.
