What is the IMEI and Why Would You Need to Repair It? The IMEI (International Mobile Equipment Identity) is a 15-digit unique number that identifies your Lenovo tablet or smartphone on a mobile network. After flashing custom ROMs, corrupting the NV (Non-Volatile) data partition, or experiencing a software crash, the IMEI can become null ( 0 or unknown ). This leaves you unable to make calls, send texts, or use mobile data.
