For that, it is important to check first if your IMEI number is nùlléd or corrupted and then go ahead for restoring the Null IMEI. Here is h0w to do that:
  • Turn your device on and go to the dialer to enter the code (*#06#) which shows up the IMEI number of the device. In case it shows 'Null', the IMEI number is corrupted and should be configured to resolve the Android No Service issue.
  • Dial (*#197328640#) or (*#*#197328640#*#*) from the handset dialer which display command mode. Users are required to select the option 'Common'.
  • Next, select the option 1 that is Field Test Mode (FTM). It should be made off if it was 'ON'. This process will change and restore the IMEI number but ensure to press the menu key button before you leave the Command screen, as this is a vital step to make the changes effective.
  • Choose key input and select option 2 which will turn off FTM.
  • Now, remove the battery and SIM card from the device, wait for 2 minutes after which re-insert the battery but not the SIM card.
  • Turn on the device and type (*#197328640#) again from the phone dial.
  • Next, go to Debug screen> phone control> Nas control> RRC and finally on RRC revision to resolve the Null IMEI or not registered on network issue.
  • Now tap on the released your phone is, which is normally option 5.
  • Turn off the phone again and insert the SIM to find out if the no service issue is resolved.
