Information provided by IMEI

  •   Mobile phone model
  •  Date of purchase
  •   year of release
  •  Warranty
  •   Kind of device -iOS /Android

When you make a call the IMEI information along with the phone number reaches the service provider.IMEI provides only device-related information and not any personal information of the owner. But it does provide a location and some network-related information.IMEI can also retrieve the call logs as when you make a call using your device the SIM sends the IMEI number with the phone number to the telecom operator.

 

How does IMEI help service providers?

GSM uses subscriber identity module cards to store subscribers’ information.

Customers can easily switch the SIM card from one device to another and start making calls without any problem

It helps operators identify valid customers and disable the devices from their end if reported lost or stolen.

IMEI is hardcoded by the manufacturer; it helps the carrier understand the capabilities of the device; it helps the provider to get the device to a nearby tower for connection.

If you lose your phone or if it gets stolen, IMEI will help you make sure the person who stole it won’t be able to use your device. The device can be denied service to any cellular network even if the SIM is changed.

T mobile with other service providers keeps a common database of blacklisted IMEI to deny service to lost or theft phones

How IMEI helps cell phone users

Whenever you buy a new phone it is recommended to keep IMEI information safe for future use.

IMEI is very useful when buying an old used phone as you can confirm that the device you are buying is:

  • Not stolen
  • Not in denied or blocked list
  • Not connected with any fraudulent activity.
  • Has no outstanding balance
  • Has no pending insurance claim

When you want to sell your old phone on any E-Commerce portal they ask you for IMEI to get all the details about the device. It helps the retailers keep track of where and when the device was sold or if it’s blacklisted.

It is always a good practice to check the IMEI number before buying a used device to validate the originality.
