What is an IMEI ?

IMEI stands for International Mobile Station Equipment Identity and it is consist of 15 decimal digit (14 digits plus a clock digit). It’s an unique identification number for GSM, UMTS, LTE devices and as well as some satellite phones.

An IMEI number helps to identify valid devices and therefore the number can be used to “blacklist” a stolen device from using that network and sometimes other networks too.

How to find my device’s IMEI number ?

There are several ways to find a device’s IMEI number –

  • The universal way to find a device’s IMEI number is by dialing *#06# from the device and a pop up will appear with it’s IMEI number.
  • Android users can check their IMEI number by going to “Settings” > “About Phone” > “Status” and will see a number under “IMEI” option .
  • Every phone on this planet comes with a IMEI number printed at the back, under battery.

What is NVRAM ?

Non-Volatile Random Access Memory, a type of memory that retains it’s contests after switching off a device. It consist of SRAM and EEPROM chips. NVRAM contains data like WiFi and Bluetooth MAC address, Baseband version, IMEI/MEID number and other essential information.
