Block Stolen Mobile Through Call

Every GSM phone has an IMEI number that is unique to it. It’s commonly printed on or underneath the battery and warranty card of the phone. The IMEI of any phone can also be obtained simply entering *#06# into the phone. The GSM network uses the IMEI number to identify valid devices, so it can be used to prevent a stolen phone from connecting to the network.

If a phone is stolen, for example, the owner can contact authorities and request that the phone’s IMEI number be used to “block” it. Regardless of whether the phone’s SIM is changed, this renders the phone worthless.
