Mobile phones have become like the third hand to us and most of us cannot imagine a life without the mobile phone. They play an integral part in our life and there is no way that we can afford to lose such a precious phone. If you have misplaced your phone in a travel, then you will not be able to find the phone if no one is around to answer the phone. All phones regardless of the generation of the phone must have an International Mobile Equipment Identity number programmed into it. In fact if your phone is lost in a bus or a train, you can use the IMEI tracking to find the route in which it is being moved. These numbers are cannot be easily changed as they are programmed into the hardware. You can use an online application to track the position of your phone.
The app uses the number to identify the phone and uses the carrier waves of the service provider to pinpoint the location of the missing phone. This can help you to get ahead of the phone to the next location at which the bus will stop and retrieve the missing phone.
