Hello sir i am using nokia 1110i mobile i lost my mobile unlock code so can pls help to remove it my mobile imei no is 356268017332142

When you forget your mobile unlock code, what you need is a master code to unlock the phone. When prompted for the unlock code, entering the master unlock code which is only unique to you mobile device by the IMEI number both unlocks the phone and resets the unlock code to the factory default of 12345.
Here, your master unlock code is 2172774176.

Hope that was helpful?
Have a lovely day.
