IMEI (International Mobile Equipment Identity) Is A 15-Digit Code That Is Specific And Unique To A Mobile Phone Authorized By GSMA. Every Phone, Unless It Is Counterfeit, Has An (IMEI). It Can Be Used To Find A Phone When It’s Lost Or Has Been Stolen. Just Like An Identity Certificate For Your Phone. Every Time A Phone Uses A Particular Network To Make Or Receive A Call, Send Or Receive A Message, Its IMEI Number Is Automatically Emitted And Tracked.
For Instance, If A Mobile Phone Is Stolen, The Owner Can Easily Call The Network Provider And Instruct Them To “Blacklist” The Phone Using Its IMEI Number Because They Have The Database. This Renders The Phone Useless On That Network, Whether Or Not The Phone’s SIM Has Been Changed For Another. In Essence, A Number Can Be Blacklisted After A Theft If The Owner Reports With IMEI Number.
