What happens to a sprint phone when is reported stolen?

When a Sprint phone is reported stolen, the carrier typically suspends the service on that device to prevent unauthorized use. The phone's IMEI number is blacklisted, making it inoperable on the Sprint network and potentially other networks as well. Additionally, the owner may be advised to contact law enforcement to file a report and recover the device. If the phone is found later, the owner can often have it reactivated, provided it hasn't been permanently blacklisted.
