To enter the unlock code in the phone, go to the menu – Settings – Tools – Phone Settings – SIM Security. SIM security code will be 4 digits and can be found in the manual of the mobile. Enter the SIM security code and then select “SIM Lock.” Navigate to the “Unlocked” option and click OK. You will be asked to enter the unlock code. Apply the code and click OK to complete the process.
Now your phone is unlocked and usable with any other operator SIM cards as well as default network also.
