IMEI numbers of cellular phones connected to a GSM network are stored in a database (EIR – Equipment Identity Register) containing all valid mobile phone equipment. so if any device if it does not have the IMEI it will not connect to the network, marked by the absence of a signal icon or unknown baseband or IMEI on the settings, and this usually occurs because installing new firmware or after performing a hard reset, fortunately for those who always make a backup before flashing or hard reset can easily restore it, for example by doing a backup via MobileuncleTool.apk, TWRP 3.0 recovery that supports EFS Backup or via ADB command.
