With the Find My Phone skill, you can ask Alexa to call your own phone as well as the phones of people you know. Say "Alexa, find my phone." The first time you do this, Alexa asks for your mobile phone number. Give your number. Alexa texts a code number to your phone to confirm you as the owner. Give the number to Alexa. Alexa rings your phone. Answer it, say hello, and a recorded message says "Glad you found your phone."

If you want to add another person to the service, say "Alexa, ask Find My Phone to add a contact." Tell Alexa the first name of the contact and that person's number. That person receives a code number by text. Read the number to Alexa. You can then say "Alexa, ask Find My Phone to call [name of contact]."
