Looking for an answer to how to unlock a network locked phone for free 2021? If so, then here is a solution for you.

If your phone SIM card is locked and you don’t want to waste any money on tools to resolve the issue, then you can ask your carrier to provide you with the unlock code to remove the SIM card lock on the Android phone

To do this, follow the below steps for how to carrier unlock Android phone free:

  • Before asking your network provider directly for the unlock code, you need to obtain the IMEI number of your phone.
  • For that, open the dialer and dial the *#06# number. 
  • Alternatively, you can go to the phone Settings.
  • Tap on the About phone.
  • Go to the Status.
  • Here, you can see the IMEI number of your SIM card. Note down this number as you will need it in the upcoming steps.
  • Now, contact your carrier or network service provider > provide them with your IMEI number.
