Sorry, but VZW can't turn on or find your phone.
You should suspend the service anytime your phone is lost or stolen. This protects you against any unauthorized charges made from your phone. You can suspend it yourself online using My Verizon, then click on the My Services tab, then click on My Phone from the menu and then click on the link for Suspend Service. Also, you can suspend it by calling Customer Care at 800-922-0204.
If you have questions about your replacement/upgrade options, or to activate a different phone on your mobile number, speak to Customer Care.
