International Mobile Equipment Identity or what is often referred to as IMEI which consists of 15 or 16 digits is usually used to identify devices that have been registered with cellular operators which will be the difference between your smartphone and mine.
While MEID is a Mobile Equipment Identifier consisting of 14 digits.
Both have the same use, except that the IMEI is the GSM version and the MEID is the CDMA version. The role of IMEI or MEID itself is really important. But sometimes because of an installation error or a wrong press or whatever, the IMEI and MEID can be lost or invalid.
There are cellphones that are very sensitive and very vulnerable and can’t just mess around with them, the Andromax Series cellphone for example.
To restore the lost or Invalid IMEI and MEID, you can try the following ways.
Find and Record IMEI or MEID
The first step you must know in advance is the IMEI or MEID number. To find out the IMEI or MEID serial number of your cellphone, open the cellphone case. Before you open the cellphone case, make sure your cellphone is turned off or off.
If you have made sure that the cellphone is turned off, you have to remove the cellphone battery. Because the position of the IMEI or MEID number is behind the battery.
After removing the battery, you will immediately see the IMEI or MEID serial number of your cellphone. Take note of the serial number of the IMEI or MEID. Whatever the amount, write it all down. If there are two, note both.
