   Contact your carrier. If you know that your phone has been stolen, you should contact your carrier immediately. Your carrier will be able to disable the service for your phone line, preventing the person who stole your phone from using your phone to make calls and texts. Your carrier can also provide you with your phone's IMEI number, which you'll need in order to file a police report. Use the following numbers to contact your carrier:

   • T-Mobile: 1-877-453-1304
   • Verizon: 1-800-922-0204
   • Sprint: 1-888-211-4727
   • AT&T Mobility: 1-800-331-0500
2. 2

   Contact your local police department. Head to your local police station or call your local non-emergency number and report your stolen phone. Give as much detail as possible, and be sure to have your phone's IMEI number handy, as most police reports require it. Not only will filing a police report potentially help get your phone back, it will allow you to file an insurance claim and prove that you didn't have your phone if fraudulent charges appear.

3. 3

   Contact insurance if necessary. If you have insurance on your phone, you can start the replacement process once you have a police report reference number. Contact your phone's insurance company for directly applicable instructions on how to get the process started.
