Have you ever lost IMEI? Usually you get this problem when you finish Flashing, Hard Reset or Factory Reset and Root on your Android.
The bad consequence of losing IMEI is that your smartphone / cellphone does not get an alias SOS signal, so you can no longer surf the internet or even just text or use the telephone. Surely it is very annoying right?
IMEI is composed of unique combination numbers, so IMEI between one smartphone and another will not be the same.
Invalid IMEI is a common problem that is often faced by most MediaTek devices including Xiaomi Redmi, Micromax, Oppo, Samsung, Vivo, HTC, Sony, etc.
Here are some ways that you can try to restore the lost IMEI number of your smartphone / cellphone. Let’s pay attention right away!
What is IMEI?
IMEI is short for International Mobile Equipment Identity and is a unique number given to each cell phone, which is usually found behind the battery.
Since 2004, IMEI has appeared in the AA-BBBBBB-05-D format. The sections labeled A and B are known as the Type Allocation Code (TAC). The TAC section of IMEI identifies the device manufacturer and model.
For example, the Google Pixel TAC code is 35-161508, while the iPhone 6s Plus is 35-332907. Some models have several TACs depending on revisions, manufacturing locations, and other factors – the iPhone 5C has a total of five different TAC codes.
The six C digits represent the unique serial number of your device, and this is determined by the handset manufacturer. Part D IMEI is a check digit that ensures that IMEI meets the Allocation and Approval Guide. Check numbers are displayed on the package to prevent incorrect IMEI from being recorded, but do not include the documented part of IMEI.
IMEI numbers of cellular phones connected to GSM networks are stored in a database (EIR Equipment Register – Equipment) which contains all valid cellular phone equipment. If the telephone is reported stolen or not approved, the number is marked invalid.
The first set of numbers is the type approval code (TAC). The first two digits represent the country code. The rest make the final assembly code. The second group identifies the producer:
- 01 and 02 = AEG
- 07 and 40 = Motorola
- 10 and 20 = Nokia
- 41 and 44 = Siemens
- 51 = Sony, Siemens, Ericsson
The third set is the serial number and the last single digit is the additional number (usually 0).
How to restore IMEI by searching for an IMEI number
