SIMLOCK feature is very important in Android and iPhone. Many of us avoid this important feature due to a lack of awareness. If the SIMLOCK feature is enabled on the smartphone, you can save yourself from potential dangers.
Before using the SIM card lock feature on an Android phone, you need to enter the specific PIN code selected by the operator first.
This passcode is often four digits long. You will find this code on the plastic card where the SIM was inserted. Be careful entering the code to avoid mistakes.
Go to the settings option of your smartphone. Then select the Security option. Here you can see an option called SIM card lock.
From here, enable the SIM card lock option and enter the digital PIN number selected by the operator.
Once the lock feature is enabled, change the SIM PIN number. The new PIN number should be such that no one can fake it. Be careful not to block when entering the old PIN.
Restart the phone after you have successfully activated the feature. Now check if the feature is working.
Remove the SIM from your smartphone and insert it into the second device. Be it iPhone or Android it can no longer be used due to a SIM block. SIM should be opened with that four-digit pin number.
This method is very effective in avoiding scammers, and if the mobile is stolen, no one can use the SIM card for negative purposes.
