Some reasons to reactivate a phone include dealing with lost or stolen property and deactivating a phone line. When a phone is lost or stolen, a consumers can deactivate their accounts with their service provider so that the thief can not use the phone. Once the phone is replaced, it will then have to be reactivated in order to be used.
When a phone bill can not be paid, or when a device will not be used for a while, a consumer can request that the line be deactivated. If the consumer wishes to reconnect the line, he will then have to have it reactivated by the service provider.
